Abstract

Differential cross sections are measured for ${}^{58, 60, 62, 64}{Ni}$ ( ${}^{18}O$ , ${}^{16}O$ ) reactions to both ground and excited ( $2^{+}$ ) states of the residual Ni nuclei at incident ${}^{18}O$ laboratory energies of 65, 57, and 50 MeV. Anomalous, forward-rising, angular distributions are seen for ${}^{58, 60}{Ni}$ ( ${}^{18}O$ , ${}^{16}O$ ) reactions, in contrast to normal heavy-ion-induced transfer shapes obtained for the heavier Ni targets. A theoretical explanation is presented based on a weaker absorption than is usually employed for such heavy-ion transfer reactions.
