Proton halo effects in the 8B+64Zn collision around the Coulomb barrier

Summary, in English

The ⁸B+⁶⁴Zn reaction at 38.5 MeV has been studied at HIE-ISOLDE CERN to investigate proton halo effect on the reaction dynamics. For the first time it was used the only existing post-accelerated ⁸B beam. The measured elastic scattering angular distribution showed a small suppression of the Coulomb-nuclear interference peak, opposite to what observed for the one-neutron halo nucleus ¹¹Be on the same target where a large suppression was observed instead. Inclusive angular and energy distributions of breakup fragments were also measured showing that, both, elastic and non-elastic breakup contribute. The presence of the additional Coulomb interactions halo-core and halo-target in ⁸B makes the reaction dynamics in this proton-halo nucleus different than the neutron-halo case. © 2023 Institute of Physics Publishing.
