Shapes of Angular Distributions of (He3,t) and (p,n). Transitions to0+Antianalog States

Abstract

The anomalous shapes of the angular distributions of tritons from the ${0}^{+}$\ensuremath{\rightarrow}${0}^{+}$ $^{3}\mathrm{He}$-induced charge-exchange transitions to antianalog states of $^{64,\phantom{\rule{0ex}{0ex}}66}\mathrm{Ga}$ and $^{40}\mathrm{K}$ can be understood on the basis of the structural relation between analog and antianalog states, together with the assumption of a pure charge-exchange (i.e., no knockout) mechanism.
