Abstract
Experimental data on Coulomb breakup and neutron removal indicate that is one of the heaviest halo nuclei discovered so far. The possible ground state of is either coming from the -wave halo or coming from the -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 projectiles at energies around 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 ground state with spin-parity .
