Description
Experimental data on Coulomb breakup and neutron removal indicate that 31Ne is the heaviest halo driven by deformation. The possible ground state of 31Ne is either 3/2- or 1/2+. To study the neutron removal from 31Ne, we use a knockout model with deformed single-particle wave functions and investigate the deformation effects on cross sections and longitudinal momentum distributions. Our numerical analysis shows a preference for the 31Ne ground state with spin-parity 3/2-.
