Abstract

The A=6 structure problem is solved within the framework of the nuclear shell model. Model states are expanded upon a basis of properly symmetrized, translationally invariant harmonic oscillator eigenstates including states of up to 6ħω of excitation. The model interaction is based upon a modification of the two-body Sussex interaction. Eigenvalues and (Jπ,T) values are predicted for the ground states of the following systems: n6, H6, He6, Li6, Be6, B6, and C6. The ground state binding energies are within 4 percent of experiment for He6, Li6, and Be6. Excited states for the He6, Li6, and Be6 systems are determined and compared to experiment and other calculations. The model spectra for the Li6 system is similar to that proposed by Ajzenberg-Selove. However, the He6 and Be6 spectra contain levels in addition to those suggested by existing compilations. In particular, the He6 and Be6 level spectra have the following level ordering: (0+,1), (2+, 1), (1+,0), (0+,1), (0+,1), (3+,0) (2+,1), (4,1), (2,1), (3,1), and (4+,1).
