摘要：
New experimental results for the elastic scattering of He-6 on Zn-64 at incident energies of 15.0 and 18.0 MeV and He-4 at 17.5 MeV along with results already published at 10.0 and 13.6 MeV, are presented. Elastic and alpha experimental cross sections are compared with coupled-reaction-channel, continuum-discretized coupled-channel, and DWBA inclusive-breakup models. The large yield of a particles observed at all measured energies can be explained by considering a nonelastic breakup mechanism.
