β delayed emission of a proton by a one-neutron halo nucleus
2011
Abstract Some one-neutron halo nuclei can emit a proton in a β decay of the halo neutron. The branching ratio towards this rare decay mode is calculated within a two-body potential model of the initial core + neutron bound state and final core + proton scattering states. The decay probability per second is evaluated for the 11 Be, 19 C and 31 Ne one-neutron halo nuclei. It is very sensitive to the neutron separation energy.
