Replacement for pages 5 8 - 1 - 4 2 , 5 8 - 1 - 4 3 , 5 9 - 1 - 7 7 through 59-1--82, and 6--2,3-137 of Nuclear Data Sheets

Explanations of conventions, symbols, and abbreviations are at the back of this issue. Policies and b a s e s for spin-parity assignments, which are used in this A-chain, are described in the front of the first i s s u e of volume B1. P l e a s e refer to a specific Nuclear Data Sheet by using the number at the bottom of the page in the following way: Nuclear Data B1-2-69(1966).

E. The Decay Scheme o f 83Sr

B. The Decay Schemes o f the 83Se Isomers

The decay scheme of 83Sr shown i s t h a t proposed by 61Ku8. The p o s i t r o n and e l e c t r o n - c a p t u r e i n t e n s i t i e s have been c a l c u l a t e d by the c o m p i l e r s from the experimental i n t e n s i t y r a t i o s f o r W2[T3 and f 3 / ~ 2 (61Ku8) and the t h e o r e t i c a l f , / f ~ ratios.

The decay schemes s h o ~ for the two 83Se isomers, complete with ~ - a n d W-energies and intensities. are those proposed by 66Ma07. The ~ - g r o u p s proposed in the decay o f 83Se g . s . a r e c o n s i s t e n t with the r e s u l t s of the f ~ - c o i n e i d e n c e experiments and with the observed ~ - s p e c t r u m (66Ma07). However. from the T - r a y i n t e n s i t y balance in t h e l e v e l scheme, the e x i s t e n c e o f the f - g r o u p t o 0.356-MeV l e v e l i s d o u b t f u l , while a f - g r o u p with i n t e n s i t y of ~6% would be r e q u i r e d to feed the 0.868-MeY l e v e l .

Mass D i f f e r e n c e s The mass d i f f e r e n c e s shown on the l e v e l scheme a r e taken from a l e a s t - s q u a r e s adjustment of masss p e c t r o m e t e r , r e a c t i o n , and decay data in t h i s mass r e g i o n . See Adjusted Mass D i f f e r e n c e s , a t the back of t h i s i s s u e , f o r a l i s t of d a t a used in the adjustment.

The e n e r g i e s of the complex f - g r o u p s i n d i c a t e d in the decay o f 69-s 83Se are those measured in the s i n g l e s - s p e c t r u m . The I n t e n s i t y of the 3.50 f - g r o u p i s e s t i m a t e d by 66Ma07 to be 25-75%. Assuming an i n t e n s i t y o f 50~ f o r t h i s group, then from the T - r a y i n t e n s i t y balance in the l e v e l scheme, the two complex f - g r o u p s (1.50. and 2.40~) are each ~ 25%.

C. The 83Se D i s i n t e g r a t i o n Energy

Correction for Drawing 2. p. BI-4-127:

The adopted 83Se Q- = 3.53. which i s sho~n on the l e v e l scheme, has been obtained from the Mass Adjustment. This number i s based on t h e f o l l o w i n g data: 1) 82Se(d.p) Q-value 2) 825e-SaKr mass d i f f e r e n c e 3) S a B r ~ - d e c a y energy

The log f t value of the 1.55~ in the decay of 83Se 9hich is given as 4.8 should be changed to 6.5 This corrected log f t value implies that the beta t r a n s i t i o n i s e i t h e r allowed or f i r s t forbidden (See Spin Assignment for SZBr 2.060 level)

The t o t a l d i s i n t e g r a t i o n energy o b t a i n e d from the f - m e a s u r e m e n t s in the decay of the two isomers a r e 3.61 from g . s . decay, and 3.5-E(SaSe i s o m e r i c l e v e l ) from i s o m e r i c s t a t e decay. According t o 82Se(d.p) experiments (65Li08) the 1/2- isomer in 8SSe i s a t 0.22 MeV. IIowever, s i n c e the u n c e r t a i n t i e s in the ~ - e n e r g y measurements with a s c i n t i l l a t i o n d e t e c t o r are r a t h e r l a r g e , t h i s d i s c r e p a n c y i s p r o b a b l y n o t too s e r i o u s . I t i s , o f c o u r s e , p o s s i b l e t h a t the ~ = I level seen by 65Li08 a t 0.22-MeV i s not the 69-s isomer, but s i n c e the a n g u l a r d i s t r i b u t i o n o f the g . s . p r o t o n group shows no i n d i c a t i o n of ~ = 1 admixture, and s i n c e the 0.22-MeV I e v e l i s the f i r s t e x c i t e d l e v e I seen in (d,p) r e a c t i o n , t h i s seems u n l i k e l y .
