Nuclear Data Sheets for

199 Pb *

BALRAJ SINGH AND GEORGE REED Department of Physics and Astronomy, McMaster University, Hamilton, Ontario, Canada, L8S 4M1 (Received July 20, 2001; Revised October 10, 2001) Abstract: The experimental nuclear structure data for

199Pb

have been compiled and evaluated. Extensive

revisions to the adopted levels, gammas and high–spin data sets for this nuclide have been made based on the new high–spin studies of 1999Po13, 1997Cl03, 1995Ne09, 1994Ba43 (also 1997Hu12,1997Fa15,1997Di03), and 1989Su12. The decay data sets and (α,3nγ) dataset have been revised but no new references are added. values are now adopted from 1995Au04. This revision supersedes earlier by 1994Ar13 (A.

µ=–1.0742 12 (1989Ra17,1986An06). Q=+0.08 9 (1989Ra17,1986An06). µ,Q: atomic–beam with LASER fluorescence spectroscopy (1986An06). ∆(199Pb–208Pb)=–0.516 fm2 4 (1986An06) from isotope shift measurements. The large change in radius from

201Pb

to

199Pb

is

ascribed to a change from f5/2 to p3/2 g.s. configurations in the two nuclides. Jπ: spin from hyperfine structure, π: µ and Q are consistent with ν 3p3/2 assignment (1983Th03). µ,Q: measured with LASER induced fluorescence spectroscopy. T1/2: from 1955An01; other: ≈80 min (1950Ne77). 0+x

%IT<100; %ε+%β+>0. Jπ: M4 γ to 0+x level; the only possible shell model states available for an M4 transition in the N=117 nucleus are the i13/2 and f5/2 states. The i13/2 probably corresponds to 424.8+x and f5/2 to 0+x level. T1/2: from 1955An01. Other: 13 min 1 (1956St05). Jπ: ν i13/2 orbital. %IT,%ε+%β+: 1978LeZA (Table of Isotopes 1978) list %IT=93, %ε+β+=7 from a priv. comm. (from authors of 1973JoZF,1974JoZX) in 1974. But a copy of this communication is no longer available from the Table of Isotopes group. E–mail queries (in July 2001) by the evaluators from two of the authors of 1973JoZF produced no response. Inspection of the gamma–ray spectrum from the decay of

199Pb

isomer

presented in 1973JoZF shows a dominant 425γ and a weak 382γ, the latter assigned to 9/2– isomer in

199Tl,

suggesting that %IT branch

is much stronger than the %ε+β+ branch. But in the absence of definitive information, the evaluators consider the decay branches as undetermined. E(level): others: 430 3 (1997Au04) based on x<9.3 (1962Ju05), 444 (1994Ba43,1999Po13) based on a proposed 19.6 level by 1978Ri04. But the existence of 19.6 level is considered as suspect since the γγ coin evidence presented by 1978Ri04 is very tentative. 1351 . 4+x 3

The partial decay scheme is that proposed by 1978Ri04 with the following changes: 1) the 3/2– state is the ground state and not at 19.58 keV as proposed by 1978Ri04; and 2) the 5/2– state is at 0+x keV (x≤9.3 keV) and not the g.s. All level energies of 1978Ri04 are therefore raised by x keV. These changes are indicated by the results of 1983Th03 (J(g.s.)=3/2–) and 1962Ju05, 1957An53 (E(5/2– level)≤9.3). For tentative γγ–coin results see table 6 of 1978Ri04. None of the excited states and γ rays above the 425+x isomer are included in the adopted levels due to the tentative nature of the decay scheme from 1978Ri04.

g.s. (see comment on Iγ for a possible problem).

From adopted levels.

γ( 1 9 9 Pb) I(γ±)=18.1 9 (relative to I(841γ)=100) corresponds to %β+≈1.0. Iγ normalization: ≈0.11 based on the following considerations: 1. I(ce+β+)(to 425.3+x level)<16% (from log f1ut>8.5); 2. ∑Iγ(unplaced)/∑Iγ(total)=0.44; 3. the proposed partial level scheme. Setting the total γ

intensity from E(level)>425.3+x to E(level)≤425.3+x as 70 20, one obtains normalization factor of 0.11 3. The

intensity of 425γ has been omitted from this calculation since the measured relative intensity is uncertain due to long T1/2=12 min and lack of reliable %IT decay from the 12.2–min 425.3+x level. Branching: %IT<2, %α=0.01. Eγ

meaningful extraction of δ. γ's. This result may be inconsistent with the decay scheme. # 1978Ri04 list seven γ's possibly in coin with the 1034.0γ; none of these γ's is the same as the three γ's in coin with the 1052.8γ, and the coin with the 720.3γ is inconsistent with the decay scheme proposed by 1978Ri04. @ Listed as 1086.79 in figure 7 of 1978Ri04. & The multipolarities of the 294.0γ, 533.1γ and 560.1γ lead to contradictory π assignments for the 1804 level according to the proposed level scheme. a The uncertainty could be greater than 20% because of the long half–life of the isomeric state (1978Ri04). b Placement of transition in the level scheme is uncertain. γ ray not placed in level scheme.

1981He07 (also 1977He06): E=35–45 MeV; measured Eγ, Iγ, excit, γ(θ), γγ, γγ(t). 1988Ro08: E=41 MeV; measured Eγ, Iγ, γ(θ), γ(θ,H,t), γγ(t). 1985St16: E=60 MeV; measured γ(θ,H,t), γ(t). Other: 1978Ri01. The level scheme is basically that of 1988Ro08, based on their experiments and the earlier results of 1985St16, 1981He07, 1978Ri01 and 1978Ri04. The evaluators have made the following changes: 1. All E(level) have been recalculated placing the 5/2– level at 0+x (x≤9.3 keV), rather than at 19.6. 2. The Eγ of the three proposed but unobserved low energy transitions have been replaced with the corresponding Eγ from the (18O,5nγ). 3. The placements of the 830.0γ and 903.6γ are from the (18O,5nγ). 199Pb
