152SM cB IB(A)$I|b(g.s.)+I|b(122 level)=82.4% 38 from 4|p|b|g (1996Gr20), in
152SM2cB excellent agreement with 82.3% 38, a sum of the individual values based
152SM3cB on intensity balances
152SM cB I|b(to g.s.)+I|b(to 122 level)=82.4 {I38} 4|p|b|g (1996GrZZ)
152SM cB IB$From the intensity imbalance at each level. For values deduced from
152SM2cB the TAGS method, see 1997Gr09
152SM cG The data of 1992Ma42 are in general agreement with earlier
152SM2cG studies. Some low intensity |g's observed by 1977Ya07, however, are
152SM3cG not confirmed by 1992Ma42, and have not been listed. Also, the energy
152SM4cG measurements of 1992Ma42 and 1977Ya07 for the high energy |g's are
152SM5cG not in very good agreement.
152SM cG E,RI$From 1992Ma42
152SM cG M,MR From adopted gammas
152SM cG E(A),RI(A)$1992Ma42 report E|g=963.3~{I2} with I|g=22.7~{I11} placed
152SM2cG from the 963 level. A transition with this energy is also known to
152SM3cG deexcite the 1086 level. From I|g/I|g(1086|g)=1.43~{I4} for the 1086
152SM4cG level in Adopted Gammas, one gets I|g=2.3~{I2} for placement from the
152SM5cG 1086 level, leaving I|g=20.4~{I11} for placement from the 963 level.
152SM6cG E|g for placement from the 1086 level is from the level energy
152SM7cG difference
152SM cG E(B)$The 861.7 and 1822.1 |g's are placed by the authors from |a 1944
152SM2cG level along with the 903.3 and 981.0 |g's; however, in (n,n'|g), the
152SM3cG 1944 level is a doublet. The evaluator has introduced that doublet
152SM4cG here, with the transitions divided as given in (n,n'|g)
152SM cL 1992Ma42: measured E|g, I|g, |g|g, |b|g|g(t) (also reported
152SM2cL in 1993MaZK)

152SM cL T$From 1992Ma42, except for the 122 level as noted
152SM cL E(Z)$The authors propose a single level at 2091 deexcited by
152SM2cL transitions 1050.1, 1127.4, and 1970.8. Based on work in (n,n'|g),
152SM3cL there is a doublet at 2091 with the 1970.8|g placed from a separate
152SM4cL level. The authors' energy gives E(level)=2092.6~{I10}. The evaluator
152SM5cL has added this second level to this dataset
