240PU c 1982Pa23: measured E|g, I|g, |g|g
240PU c Other: 1967Wa27.
240PU cB IB$The |b feedings are poorly known for most levels since the
240PU2cB multipolarities and mixing ratios of |g-ray transitions are not well
240PU3cB established, thus all feedings, except that for 1309 keV level are
240PU4cB treated as uncertain and given mostly without uncertainties. From K|p
240PU5cB assignments, only the strong feeding to the topmost level at 1309 keV
240PU6cB is definite with |DK=0. All other feedings are less likely since
240PU7cB these involve a high degree of K-forbiddenness with |DK=2 to 5.
240PU8cB Apparent large intensity imbalances for some of the levels suggests
240PU9cB that the decay scheme is incomplete.
240PU cG M(A)$Intensity balance is consistent with mult=E1,E2 or M1. Adopted
240PU2cG J|p values rule out mult=E1.
240PU cG M(B)$From Adopted Gammas.
240PU cG M(D)$Intensity balance is consistent with mult=E1,E2 or M1. Adopted
240PU2cG J|p values rule out mult=M1,E2.
240PU cG RI(F)$Deduced from I(|g+ce) intensity balance.
240PU cG E(X)$Placement from 1177 level proposed during evaluation to seek
240PU2cG some intensity balance at 1030 keV. 1982Pa23 proposed placement from
240PU3cG only the 1309 keV level. The |DK=4 involved for a transition from
240PU4cG 1309-keV level to 1161-keV level suggests placement by 1982Pa23 is
240PU5cG less likely

240PU cN NR$1982Pa23 measure absolute |g-ray intensity of 27.6 {I14} for
240PU2cN 566|g. If the |g-ray intensities are treated as relative then
240PU3cN normalization factor=0.935 {I18}, assuming, as expected, no |b
240PU4cN feeding to the 4+ and 6+ members of the g.s. band due to large |DK=5
240PU5cN involved. This normalization factor gives absolute intensity of 25.8
240PU6cN {I14} for the 566|g, in reasonable agreement with 27.6 {I14} from
