Abstract

Experimental data on Coulomb breakup and neutron removal indicate that Ne31 is one of the heaviest halo nuclei discovered so far. The possible ground state of Ne31 is either 3/2 coming from the p-wave halo or 1/2+ coming from the s-wave halo. In this work, we develop a treatable model to include deformed wave functions and a dynamical knockout formalism that includes the dependence on the nuclear orientation to study the neutron removal from Ne31 projectiles at energies around E200 MeV/nucleon. A detailed account of the effects of deformation on cross sections and longitudinal momentum distributions is made. Our numerical analysis indicates a preference for the Ne31 ground state with spin-parity 3/2.
