摘要：

The Ge-66 and Ge-68 nuclei are studied by means of the shell model with the extended P+QQ Hamiltonian, which succeeds in reproducing experimentally observed energy levels, moments of inertia, and other properties. The investigation using the reliable wave functions predicts T=0,J=9 one-proton-one-neutron (1p1n) alignment in the g(9/2) orbit, at high spins (14(1)(+), 16(1)(+), and 18(1)(+)) in these Napproximate toZ even-even nuclei. It is shown that a series of the even-J positive-parity yrast states (observed up to 26(1)(+) for Ge-68) consists of the ground-state band and successive three bands with different types of particle alignments (two-neutron, 1p1n, two-proton-two-neutron) in the g(9/2) orbit.
