Helium nuclei around the neutron drip line

Abstract

Neutron rich He nuclei have been investigated using relativistic mean field approach in co-ordinate space. Elastic partial scattering cross sections for proton scattering in inverse kinematics have been calculated using the theoretically obtained density for ${}^{6,8}$He and compared with experiment. The energies of the low-lying resonance states in the neutron unstable nuclei ${}^{5,7}$He have also been calculated and compared with experimental observations.
