152GD cG E,RI$From 1973MeXQ, except where noted otherwise. The evaluator has
152GD2cG increased the author's values by 8 eV to correct for a change in the
152GD3cG energy of the 412 Au standard from 411.794, used by 1973MeXQ, to
152GD4cG 411.80205~{I17} (2000He14). At the same time, based on a comparison of
152GD5cG the author's values with later work, 1990Me15, and with the value for
152GD6cG the 368|g of 1984Bu35, the evaluator has increased the uncertainty in
152GD7cG the author's values to a minimum of 70 eV. For the I|g values, the
152GD8cG evaluator has added in quadrature an uncertainty of 2% to account for
152GD9cG the uncertainty in the efficiency curve
152GD cG M,MR$From Adopted Gammas. Mult data from this dataset are given in
152GD2cG comments. The |a(K)exp are from the adopted I|g's and a weighted
152GD3cG average of Ice(K) data of 1979Ar16, 1975Sc32, and 1960Ma11, normalized
152GD4cG to |a(K)exp(344|g)=0.03103 (E2 theory)
152GD cG E(A),RI(A)$No deexciting transitions are observed from the 1109 level;
152GD2cG however, this level is fed by the 647|g from the 1756 level. using the
152GD3cG known decay properties from the 1109 level as given in Adopted Gammas,
152GD4cG and if there is no direct |b{+-} feeding of the 1109 level, an
152GD5cG intensity balance gives the I|g values shown. The energies are
152GD6cG rounded-off values from Adopted Gammas
152GD cG E(B),RI(B)$No deexciting transitions are observed from the 1123 level;
152GD2cG however, this level is fed by the 192|g from the 1314 level and by the
152GD3cG 633|g from the 1756 level. using the known decay properties from the
152GD4cG 1123 level as given in Adopted Gammas, and if there is no direct |b{+-}
