Single proton removal reactions in proton halo nuclei

Ravinder Kumar


The single proton breakup through stripping and diffraction reactions from weakly bound state in an exotic nucleus (8B) on a heavy target (Pb) at 72 AMeV energy have been studied. In order to elucidate the differences with the well-understood neutron breakup mechanism the dynamics of proton nuclear breakup is compared to that of an equivalent neutron of higher binding energy. The parallel momentum distributions (LMD) and breakup cross sections for stripping and diffraction mechanisms have been calculated and observed that in nuclear breakup mechanism the proton behaves exactly as a neutron of higher binding energy. We hope that the present study might be helpful for better understanding of the dynamics of proton halo nuclei.
