Breakup mechanisms in the He 6 + Zn 64 reaction at near-barrier energies
New experimental results for the elastic scattering of 6 He on 64Zn at incident energies of 15.0 and 18.0 MeV and 4 He at 17.5 MeV along with results already published at 10.0 and 13.6 MeV, are presented. Elastic and α experimental cross sections are compared with coupled-reaction-channel, continuum-discretized coupledchannel, and DWBA inclusive-breakup models. The large yield of α particles observed at all measured energies can be explained by considering a nonelastic breakup mechanism. ; This work was partially supported by the Spanish Ministerio de Economía y Competitividad and FEDER funds (Projects No. FIS2014-53448-C2-1-P, No. FIS2017-88410-P, and No. FPA2016-77689-C2-1-R) and by the European Union's Horizon 2020 research and innovation program under Grant Agreement No. 654002. ; Peer reviewed
