A cluster model of $^{6}$He

ORAL

Abstract

Small nuclei provide an ideal testing ground of few-body theories. $^{6}$He is particularly interesting in that it shows an extended particle distribution similar to a halo nucleus, is loosely bound, and is a Borromean system. We apply the Brink Formalism in secondary quantization to study the structure of $^{6}$He. This formalism allows for the proper treatment of Fermi statistics and correct projection into eigenstates of angular momentum. The alpha plus dineutron configuration and ``cigar'' (neutron, alpha, neutron chain) configuration were studied to obtain binding energies, charge radii, matter radii, and B(E2) for $^{6}$He. We discuss the relative weight of both configurations as well as the size of the interference term between them in the overall $^{6}$He wavefunction.
