(p, d) and (p, t) Reactions on the Zn Isotopes at 17.5 MeV

Abstract

Angular distributions of the differential cross section for the ($p, d$) and ($p, t$) reactions on the five stable Zn isotopes, ${\mathrm{Zn}}^{64,66,67,68,70}$, were obtained using 17.5-MeV protons. Between 9 and 15 deuteron groups were investigated for each isotope. Pickup of neutrons from the $1f_{\frac{5}{2}}$, $2p_{\frac{3}{2}}$, $2p_{\frac{1}{2}}$, and $1g_{\frac{9}{2}}$ subshells indicates considerable configuration mixing in the ground-state wave functions of the target nuclei. Several cases of "$J$ dependence" were observed. Distorted-wave Born approximation calculations were carried out and spectroscopic factors and occupation numbers are presented.
