Abstract
A simple five-body cluster orbital shell model approximation is proposed to describe the ground state wave function of the neutron-halo nucleus. The spatial angular correlations, the geometry of the system, the α-particle, and the valence neutron momentum distribution are calculated analytically. With a single free parameter the model is able to reproduce the experimental geometry of as well as the experimental transverse momentum distribution of the nucleus from fragmentation on a carbon target, at high energy.
