139ND2cN |SI(|g+ce)(822.1|g+827.8|g+852|g)=100. It is assumed
139ND3cN that there is no direct |e+|b{++} feeding to the g.s. and the 113.87
139ND4cN level. Value of I(|g+ce) for 231|g (in {+139}Nd IT decay) is deduced
139ND5cN in two ways: 1. from measured I|g(231|g)=2.35 {i20} (average of values
139ND6cN from 1971Bu22 and 1969Be64); 2. from I(ceK) data for 231|g, I|g and
139ND7cN I(ceK) data for five strong |g rays (1971Bu22) in {+139}Pr were used
139ND7cN to determine an average conversion factor of 43.1 {i25} to normalize
139ND8cN the ce(K) and I|g data in 1971Bu22 on the same scale, which is then
139ND9cN used to obtain I(|g+ce) for 231|g. Values of branching ratios are:
139NDAcN 87.2% {i11} using measured I|g of 231|g and 86.6% {i15} from measured
139NDBcN I(ceK) value of 231|g. Weighted average of the two results is
139NDCcN 87.0% {i10} for %(|e+|b{++}), and 13.0 {i10} for IT decay.
