We have investigated the loosely bound halo candidate in a neutron + core coupling model. A deformed Woods-Saxon potential is used for the neutron-core interaction and the coupled channels equations are solved with Sturmian expansions of the relative motion wave functions for experimental neutron separation energy. Longitudinal momentum distributions, the r.m.s. matter radius, the neutron stripping cross-section and the electromagnetic dissociation cross-section are calculated and compared with the sparse available data. An assessment of the possible character of is made, and in particular, of the role of s-orbital motion between halo-neutron and core.
