B. The Decay Scheme of 145Ce
D. The Decay Schemes of 145pm and 145Sm
The decay scheme shown i s t h a t proposed by 66Ho10. Since no g r o u n d f s t a t e ~-group has been seen, the y - i n t e n s i t i e s have been normalized so t h a t t h e sum f o r t h o s e feeding the 145pr g . s . i s 100. The i n t e n s i t y of the 0.0638 t r a n s i t i o n was o b t a i n e d on the assumption t h a t the 0.0638~ i s M1. The i n t e n s i t i e s of the ~ - g r o u p s have been c a l c u l a t e d to give an i n t e n s i t y balance at each l e v e l . The sum of t h e ~ - i n t e n s i t i e s c a l c u l a t e d in t h i s way i s ~I00%. The low log f t values f o r t h e ~ - g r o u p s to the 0.785 and 1.21 l e v e l s show t h a t t h e s e t r a n s i t i o n s are allowed. Although the spin of i45Ce i s not known, the p a r i t y must be n e g a t i v e (from the s h e l l model). Therefore, the 0.785 and 1.21 l e v e l s must also have n e g a t i v e p a r i t y . Again from t h e s h e l l model, the i45pr ground s t a t e and low-lying s t a t e s a r e expected to have p o s i t i v e p a r i t y (ds/2 and g7/2 s t a t e s ) . N e g a t i v e - p a r i t y s t a t e s r e q u i r e the p a r t i c i p a t i o n of the h i g h - l y i n g hl~/2 proton s t a t e e i t h e r as a pure c o n f i g u r a t i o n , or coupled with the l o w e r - l y i n g = + s t a t e s . The low log f t v a l u e s can be u n d e r s t o o d ! i n terms o f the change of an h9/2 neutron i n t o an h i i / 2 p r o t o n i f the ~45Ce ground s t a t e i s hg/2 r a t h e r than the expected f~/2 (see 149Sm) or ( f 7 / 2 ) ~ / 2 (see i47Nd). See a l s o Comment B, Comp i l e r s ' A n a l y s i s f o r g = 146.

C. The Decay Scheme of 145pr The decay scheme shown i s t h a t proposed by 59D71. The t r a n s i t i o n i n t e n s i t i e s per 100 decays of i45pr were o b t a i n e d from the measured photon i n t e n s i t y of 0.20 per 100 ~ ' s f o r the 0.0727, a =3.75 f o r the 0.0727, and the r e l a t i v e photon i n t e n s i t i e s . The i n t e n s i t i e s of t h e ~ - g r o u p s have been c a l c u l a t e d to give an i n t e n s i t y balance a t each l e v e l . The i n t e n s i t y of the g r o u n d - s t a t e ~ - g r o u p c a l c u l a t e d in t h i s way i s 98.3%, in agreement with the measured value o f >95%.
N u c l e a r Data
The decay scheme f o r 145pm i s based on the r e s u l t s of 59B165. The d i s i n t e g r a t i o n energy, Q+= 0.141 10, was found from CLMN/~K= 0,85 3 with the help of t h e curves of Brysk and Rose, From Q+, the r a t i o CK/ELMN f o r the 0.072 l e v e l and f o r t h e ground s t a t e were found. These r a t i o s were used with the e x p e r i m e n t a l l y determined r a t i o s G x ( g . s . ) / ¢ K ( e x c i t e d s t a t e s ) = 5.9 and (0.072 t r a n s i t i o n ) / ( 0 . 0 6 7 t r a n s i t i o n ) = I. 36 to o b t a i n the percentage of e l e c t r o n c a p t u r e to the ground s t a t e and e x c i t e d s t a t e s .

From the d i s i n t e g r a t i o n energy, Q+= 0.630 13, OK/eLMN f o r the ground s t a t e was found t o be 5.9, This was used with the r a t i o ~ K ( g . s . ) / ¢ i ( 0 . 0 6 1 4 0 l e v e l ) = 0.08 2 and the r e l a t i v e t r a n s i t i o n i n t e n s i t y of the 0.00140~ and 0,495~ to o b t a i n the p e r c e n t a g e o f e l e c t r o n c a p t u r e to the ground s t a t e and e x c i t e d s t a t e s .
E. The Level Scheme of 145Nd The 145pr decay scheme s u g g e s t s t h a t the s i n g l e peaks seen in Coulomb e x c i t a t i o n of the 0.92 and 1.05 l e v e l s are p r o b a b l y d o u b l e t s . The 0.071 peak p r o b a bly i n c l u d e s 7 ' s from both the 0.067 and 0.072 levels. The l e v e l scheme of 145Nd, with t h r e e n e u t r o n s o u t s i d e the closed s h e l l at 82, i s c h a r a c t e r i z e d by two lowl y i n g e x c i t e d l e v e l s s e p a r a t e d from the next l e v e l b y = 0 . 7 MeV: In 147Sm, a s i m i l a r s i t u a t i p n occurs, the energy "gap" in t h i s case b e i n g ~ 0 . 6 MeV. In each case, the g r o u n d - s t a t e s p i n has been measured to be 7/2. In 147Sm, the o t h e r two l o w - l y i n g s t a t e s have been i n t e r p r e t e d as ( f 7 / 2 ) ~ with J = 5/2 and 3/2 (65Ke09) or as t h e J =5/2 and 3/2 members of the q u i n t e t o f s t a t e s formed by coupling t h e f7/2 s h e l l model s t a t e with the 2 + quadrupole s t a t e of the n e i g h b o r i n g even Sm i s o t o p e s (64Me17, 65Ke09). In both models t h e J =3/2 and J = 5 / 2 s t a t e s are lowest. For 145Nd, the e x i s t i n g conversion and h a l f - l i f e d a t a are c o n s i s t e n t with, but do not demand, the a s s i g n ment of 3/2- and 5/2- to the 0.067 and 0.072 l e v e l s , r e s p e c t i v e l y . From aK, the 0.067 and 0.072 T ' s are M1, E2, or MI+E2. From K/L, the 0.0727 i s mainly M1, .'. the 0.072 l e v e l i s a s s i g n e d J =5/2.

F. The Decay Scheme o f 145Eu
G, The Decay Scheme o f 145Gd
Level schemes have been proposed by 67Ad02 and by 67Hi05. In a d d i t i o n , 67Dr01 h a s deduced a number o f l e v e l s by comparison of t h e 145Eu decay d a t a with t h e l e v e l s seen in 144Sm(d,p). The l e v e l scheme shown h e r e h a s been c o n s t r u c t e d by t h e c o m p i l e r s from t h e work o f t h e above a u t h o r s . I t s h o u l d be noted t h a t 67Ad02 h a s a l e v e l a t 1.005 r a t h e r t h a n a t 1.4365 o b t a i n e d by i n t e r c h a n g i n g t h e r e l a t i v e o r d e r o f t h e 0.1109 and 0 . 5 4 2 5 ~ ' s . T h e i r placement of t h e s e gammas was b a s e d mainly on t h e i r c o n c l u s i o n t h a t t h e O. l l 0 9 W w a s more i n t e n s e t h a n t h e 0.5425~. A comparison o f t h e i r r e l a t i v e photon i n t e n s i t i e s with t h o s e o f o t h e r a u t h o r s shows t h a t t h e i r pho5on i n t e n s i t y f o r t h e 0.1109 i s t o o h i g h by a f a c t o r o f about 2. A f u r t h e r argument a g a i n s t t h e e x i s t e n c e o f a l e v e l a t 1.005 comes from t h e 144Sm(d,p) work. 65Ke09 r e p o r t s a l e v e l a t 1.004 but c l a i m s t h a t i t can be e n t i r e l y a c c o u n t e d f o r a s an i m p u r i t y . The T- and ~ - i n t e n s i t i e s have been n o r m a l i z e d to g i v e 100 decays t o t h e 145Sm ground s t a t e . T h i s n o r m a l i z a t i o n g i v e s an i n t e n s i t y o f 67% f o r t h e 0.894~7, in good agreement with t h e measured v a l u e o f 68% 14 found by 66Zh01. However, t h i s n o r m a l i z a t i o n l e a d s t o an i n t e n s i t y imbalance a t t h e 0.8940 l e v e l (67 out~ 53 i n ) , and g i v e s only 84% f o r t h e t o t a l ( ~ + e ) - d e c a y from 145Eu. I f t h e decay scheme i s c o r r e c t , t h e n t h e above d i s c r e p a n c i e s may be due to an i n c o r r e c t v a l u e f o r t h e i n t e n s i t y r a t i o ~1/~2. I f t h e t o t a l ~ + - i n t e n s i t y i s h e l d f i x e d a t 2.0% ( t h e v a l u e o b t a i n e d from V~/0.8940T), t h e n a v a l u e o f =0.9 f o r ~1/~2 i s n e e d e d to g i v e t h e r e q u i r e d f e e d i n g to t h e 0.8940 l e v e l and to g i v e =100% f e r t h e t o t a l ( ~ + e ) - d e c a y . T h i s r a t i o i s tO be compared with t h e measured v a l u e s o f 0.32 f o r 670b03 and 0.40 f o r 67Hi05. The a n g u l a r c o r r e l a t i o n s i n v o l v i n g t h e 1.4365 l e v e l give inconsistent conclusions regarding the spin of t h i s l e v e l . (0.1109~/)(0.542579(~) shows, f o r t h e s p i n sequence 3/2(D,Q)J(D)3/2, t h a t J = 1/2 ( f o r any ~), 3 / 2 i f ~ = - 0 . 2 6 , o r 5/2 i f ~ = + 0 . 1 9 . (0.5425T)(0.8940T)(8) shows, f o r t h e s p i n sequence J(D)3/2(Q)7/2, t h a t J =1/2 i f A2 = - 0 . 0 7 !(66Go08) or 3/2 i f A 2 = + 0 . 0 4 (670b03), J f5/2. F i n a l l y , (0. 1109)/) (0.89407) (#) shows, f o r t h e s p i n s e q u e n c e 3/2(D, Q)J [J(D)3/2] 3/2(Q)7/2 (where t h e i n t e r m e d i a t e 0.54259/ i s u n o b s e r v e d ) , t h a t J = 5 / 2 i f 0 . 7 5 ~ 4 . 3 , J ~1/2, 3/2.
The decay scheme shown i s proposed by t h e c o m p i l e r s . The W t - , XK- and w - i n t e n s i t y d a t a o f 59G123 and 59023 imply a ( ~ + + 6 ) - t r a n s i t i o n to t h e 1.760 and 1.882 l e v e l s of i n t e n s i t y ! = 6 6 ~ . I f t h e ~ + in t h i s t r a n s i t i o n h a s e n e r g y 2.5 MeV, then Q+= 5.3. This Qv a l u e i s in agreement with p r e d i c t i o n s from s y s t e m atics. However, there are not many data points in this region. There seems to be no evidence for a very energetic ~ + which should be present if there is decay to lowlying 145Eu states~ Therefore, the other =34% of the 145Gd d e c a y s must o c c u r by e l e c t r o n c a p t u r e t o levels higher than =1.8, If this analysis is c o r r e c t , a s p i n and p a r i t y o f 3 / 2 + f o r t h e ground s t a t e o f 145Gd, which i s s t r o n g l y s u g g e s t e d by t h e s h e l l model for~81 n e u t r o n s , i s r u l e d out.

B. The Decay Scheme of 145Ce
D. The Decay Schemes of 145pm and 145Sm
The decay scheme shown i s t h a t proposed by 66Ho10. Since no g r o u n d f s t a t e ~-group has been seen, the y - i n t e n s i t i e s have been normalized so t h a t t h e sum f o r t h o s e feeding the 145pr g . s . i s 100. The i n t e n s i t y of the 0.0638 t r a n s i t i o n was o b t a i n e d on the assumption t h a t the 0.0638~ i s M1. The i n t e n s i t i e s of the ~ - g r o u p s have been c a l c u l a t e d to give an i n t e n s i t y balance at each l e v e l . The sum of t h e ~ - i n t e n s i t i e s c a l c u l a t e d in t h i s way i s ~I00%. The low log f t values f o r t h e ~ - g r o u p s to the 0.785 and 1.21 l e v e l s show t h a t t h e s e t r a n s i t i o n s are allowed. Although the spin of i45Ce i s not known, the p a r i t y must be n e g a t i v e (from the s h e l l model). Therefore, the 0.785 and 1.21 l e v e l s must also have n e g a t i v e p a r i t y . Again from t h e s h e l l model, the i45pr ground s t a t e and low-lying s t a t e s a r e expected to have p o s i t i v e p a r i t y (ds/2 and g7/2 s t a t e s ) . N e g a t i v e - p a r i t y s t a t e s r e q u i r e the p a r t i c i p a t i o n of the h i g h - l y i n g hl~/2 proton s t a t e e i t h e r as a pure c o n f i g u r a t i o n , or coupled with the l o w e r - l y i n g = + s t a t e s . The low log f t v a l u e s can be u n d e r s t o o d ! i n terms o f the change of an h9/2 neutron i n t o an h i i / 2 p r o t o n i f the ~45Ce ground s t a t e i s hg/2 r a t h e r than the expected f~/2 (see 149Sm) or ( f 7 / 2 ) ~ / 2 (see i47Nd).

C. The Decay Scheme of 145pr The decay scheme shown i s t h a t proposed by 59D71. The t r a n s i t i o n i n t e n s i t i e s per 100 decays of i45pr were o b t a i n e d from the measured photon i n t e n s i t y of 0.20 per 100 ~ ' s f o r the 0.0727, a =3.75 f o r the 0.0727, and the r e l a t i v e photon i n t e n s i t i e s . The i n t e n s i t i e s of t h e ~ - g r o u p s have been c a l c u l a t e d to give an i n t e n s i t y balance a t each l e v e l . The i n t e n s i t y of the g r o u n d - s t a t e ~ - g r o u p c a l c u l a t e d in t h i s way i s 98.3%, in agreement with the measured value o f >95%.
N u c l e a r Data
The decay scheme f o r 145pm i s based on the r e s u l t s of 59B165. The d i s i n t e g r a t i o n energy, Q+= 0.141 10, was found from CLMN/~K= 0,85 3 with the help of t h e curves of Brysk and Rose, From Q+, the r a t i o CK/ELMN f o r the 0.072 l e v e l and f o r t h e ground s t a t e were found. These r a t i o s were used with the e x p e r i m e n t a l l y determined r a t i o s G x ( g . s . ) / ¢ K ( e x c i t e d s t a t e s ) = 5.9 and (0.072 t r a n s i t i o n ) / ( 0 . 0 6 7 t r a n s i t i o n ) = I. 36 to o b t a i n the percentage of e l e c t r o n c a p t u r e to the ground s t a t e and e x c i t e d s t a t e s .

From the d i s i n t e g r a t i o n energy, Q+= 0.630 13, OK/eLMN f o r the ground s t a t e was found t o be 5.9, This was used with the r a t i o ~ K ( g . s . ) / ¢ i ( 0 . 0 6 1 4 0 l e v e l ) = 0.08 2 and the r e l a t i v e t r a n s i t i o n i n t e n s i t y of the 0.00140~ and 0,495~ to o b t a i n the p e r c e n t a g e o f e l e c t r o n c a p t u r e to the ground s t a t e and e x c i t e d s t a t e s .
E. The Level Scheme of 145Nd The 145pr decay scheme s u g g e s t s t h a t the s i n g l e peaks seen in Coulomb e x c i t a t i o n of the 0.92 and 1.05 l e v e l s are p r o b a b l y d o u b l e t s . The 0.071 peak p r o b a bly i n c l u d e s 7 ' s from both the 0.067 and 0.072 levels. The l e v e l scheme of 145Nd, with t h r e e n e u t r o n s o u t s i d e the closed s h e l l at 82, i s c h a r a c t e r i z e d by two lowl y i n g e x c i t e d l e v e l s s e p a r a t e d from the next l e v e l b y = 0 . 7 MeV: In 147Sm, a s i m i l a r s i t u a t i p n occurs, the energy "gap" in t h i s case b e i n g ~ 0 . 6 MeV. In each case, the g r o u n d - s t a t e s p i n has been measured to be 7/2. In 147Sm, the o t h e r two l o w - l y i n g s t a t e s have been i n t e r p r e t e d as ( f 7 / 2 ) ~ with J = 5/2 and 3/2 (65Ke09) or as t h e J =5/2 and 3/2 members of the q u i n t e t o f s t a t e s formed by coupling t h e f7/2 s h e l l model s t a t e with the 2 + quadrupole s t a t e of the n e i g h b o r i n g even Sm i s o t o p e s (64Me17, 65Ke09). In both models t h e J =3/2 and J = 5 / 2 s t a t e s are lowest. For 145Nd, the e x i s t i n g conversion and h a l f - l i f e d a t a are c o n s i s t e n t with, but do not demand, the a s s i g n ment of 3/2- and 5/2- to the 0.067 and 0.072 l e v e l s , r e s p e c t i v e l y .

F. The Decay Scheme o f 145Eu

Level schemes have been proposed by 67Ad02 and by 67Hi05. In a d d i t i o n , 67Dr01 h a s deduced a number o f l e v e l s by comparison of t h e 145Eu decay d a t a with t h e l e v e l s seen in 144Sm(d,p). The l e v e l scheme shown h e r e h a s been c o n s t r u c t e d by t h e c o m p i l e r s from t h e work o f t h e above a u t h o r s .

A comparison o f t h e i r r e l a t i v e photon i n t e n s i t i e s with t h o s e o f o t h e r a u t h o r s shows t h a t t h e i r pho5on i n t e n s i t y f o r t h e 0.1109 i s t o o h i g h by a f a c t o r o f about 2. A f u r t h e r argument a g a i n s t t h e e x i s t e n c e o f a l e v e l a t 1.005 comes from t h e 144Sm(d,p) work. 65Ke09 r e p o r t s a l e v e l a t 1.004 but c l a i m s t h a t i t can be e n t i r e l y a c c o u n t e d f o r a s an i m p u r i t y . The T- and ~ - i n t e n s i t i e s have been n o r m a l i z e d to g i v e 100 decays t o t h e 145Sm ground s t a t e . T h i s n o r m a l i z a t i o n g i v e s an i n t e n s i t y o f 67% f o r t h e 0.894~7, in good agreement with t h e measured v a l u e o f 68% 14 found by 66Zh01. However, t h i s n o r m a l i z a t i o n l e a d s t o an i n t e n s i t y imbalance a t t h e 0.8940 l e v e l (67 out~ 53 i n ) , and g i v e s only 84% f o r t h e t o t a l ( ~ + e ) - d e c a y from 145Eu. I f t h e decay scheme i s c o r r e c t , t h e n t h e above d i s c r e p a n c i e s may be due to an i n c o r r e c t v a l u e f o r t h e i n t e n s i t y r a t i o ~1/~2. I f t h e t o t a l ~ + - i n t e n s i t y i s h e l d f i x e d a t 2.0% ( t h e v a l u e o b t a i n e d from V~/0.8940T), t h e n a v a l u e o f =0.9 f o r ~1/~2 i s n e e d e d to g i v e t h e r e q u i r e d f e e d i n g to t h e 0.8940 l e v e l and to g i v e =100% f e r t h e t o t a l ( ~ + e ) - d e c a y . T h i s r a t i o i s tO be compared with t h e measured v a l u e s o f 0.32 f o r 670b03 and 0.40 f o r 67Hi05. The a n g u l a r c o r r e l a t i o n s i n v o l v i n g t h e 1.4365 l e v e l give inconsistent conclusions regarding the spin of t h i s l e v e l .

The decay scheme shown i s proposed by t h e c o m p i l e r s . The W t - , XK- and w - i n t e n s i t y d a t a o f 59G123 and 59023 imply a ( ~ + + 6 ) - t r a n s i t i o n to t h e 1.760 and 1.882 l e v e l s of i n t e n s i t y ! = 6 6 ~ . I f t h e ~ + in t h i s t r a n s i t i o n h a s e n e r g y 2.5 MeV, then Q+= 5.3. This Qv a l u e i s in agreement with p r e d i c t i o n s from s y s t e m atics. However, there are not many data points in this region. There seems to be no evidence for a very energetic ~ + which should be present if there is decay to lowlying 145Eu states~ Therefore, the other =34% of the 145Gd d e c a y s must o c c u r by e l e c t r o n c a p t u r e t o levels higher than =1.8, If this analysis is c o r r e c t , a s p i n and p a r i t y o f 3 / 2 + f o r t h e ground s t a t e o f 145Gd, which i s s t r o n g l y s u g g e s t e d by t h e s h e l l model for~81 n e u t r o n s , i s r u l e d out. An a s s i g n m e n t o f s l / 2 would account f o r t h e a b s e n c e o f the ground-statefi%transition. However, more d a t a a r e needed b e f o r e any f i r m c o n c l u s i o n s can be drawn.

The mass differences shown on the level schemes are taken from a least-squares adjustment of massspectrometer, reaction, and decay data in this mass region. See Adjusted Mass Differences at the back of this issue for a list of data used in the adjustment.
