A cluster model of 6He and 6Li

Small nuclei provide an ideal testing ground of few-body theories. He-6 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 a fully antisymmetric model with correct projection into eigenstates of angular momentum. Binding energies, charge radii, matter radii, and B(E2; 0(+)-> 2(+)) were obtained for the alpha+2n and cigar configurations. The same configurations were used to obtain the same observables for Li-6. Were were then able to calculate the log ft value for the beta decay of He-6.
