ReactionSn116(α, He3)at 65.7 MeV

Differential cross sections for ${}_{}{}^{116}{}_{}{}^{}\mathrm{Sn}(\alpha , {}_{}{}^3{}_{}{}^{}\mathrm{He})$ with 65.7-MeV $\alpha$ particles were measured from 15° to 80°. Data were obtained for ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ groups corresponding to excitation energies of 0.0, 0.16, 0.32, 0.72, 1.03, 1.25, 1.58, and 3.20 MeV in ${}_{}{}^{117}{}_{}{}^{}\mathrm{Sn}$. The angular distributions were well fitted by zero-range distorted-wave predictions. The spectroscopic factors are generally in good agreement with those obtained in a ($d, p$) experiment.
