Population of0+Excited States inPu238andPu240by Single-Neutron Transfer Reactions

Abstract

Studies of the single-particle transfer reactions ${}_{}{}^{239}{}_{}{}^{}\mathrm{Pu}(d, p){}_{}{}^{240}{}_{}{}^{}\mathrm{Pu}$ and ${}_{}{}^{239}{}_{}{}^{}\mathrm{Pu}(d, t){}_{}{}^{238}{}_{}{}^{}\mathrm{Pu}$ indicate that—contrary to theoretical expectations—the ratios of the cross sections for population of the $K^{\pi }=0^{+}$ excited states to those for population of the ground states are of the same order of magnitude as the ratios for the equivalent ($p, t$) reactions.
