Phys. Rev. C 50, R1–R4 (1994)Simplified α+4n model for the 8He nucleus
A simple five-body cluster orbital shell model approximation is proposed to describe the ground state wave function of the 8He 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 8He as well as the experimental transverse momentum distribution of the 6He nucleus from 8He fragmentation on a carbon target, at high energy. © 1994 The American Physical Society URL:
