摘要: Abstract The cumulative yields of the 111Pd isomers have been measured in fission 232Th, 233U, 235U, 238U and 239Pu by neutrons. ratios 11 2 metastable state yield to 5 ground are 0·0043, 0·0209, 0·0096, 0·0048 0·0186 for respective nucleides. estimated error each value is ±10%. Independent isomeric calculated various assumptions charge distribution. results these calculations discussed terms parameters which describe dispersion mass-chain 111 angular momentum with fragments formed. An upper limit 0·43% has placed on β-decay branch 111Rh111mPd.
