Abstract

The A = 5 structure problem is solved within the framework of the nuclear shell model. The model states are expanded on a basis of properly symmetrized translationally invariant harmonic oscillator eigenstates including states of up to 5(kh)gw of oscillator excitation. Ground and excited levels of the 5H, 5He, 5Li and 5Be systems are presented. The two-body interaction is based on the Sussex matrix elements. Model results are in good agreement with measured A = 5 level positions. The model T = 32 results lead to a quartet of levels, whose positions are given roughly by the isobaric multiplet mass equation.
