Abstract
The and nuclei are studied by means of the shell model with the extended Hamiltonian, which succeeds in reproducing experimentally observed energy levels, moments of inertia, and other properties. The investigation using the reliable wave functions predicts , one-proton–one-neutron alignment in the orbit, at high spins (, , and ) in these even-even nuclei. It is shown that a series of the even- positive-parity yrast states (observed up to for ) consists of the ground-state band and successive three bands with different types of particle alignments (two-neutron, , two-proton–two-neutron) in the orbit.
