High-spin states in {sup 68}Ge and {sup 72}Se have been studied by in-beam, gamma-ray spectroscopy. In {sup 68}Ge the three known bands beginning at 8{sup +} are found to exhibit crossing transitions and other new positive-parity bands are discovered to feed into them. In {sup 72}Se only a single positive-parity yrast band is seen to high spin. Detailed, more realistic microscopic model calculations have been carried out for {sup 68}Ge and {sup 72}Se. There is striking agreement between the calculations and the new data for {sup 68}Ge, including a predicted new band with superdeformation, {beta}{similar to}0.42. The calculations for {supmore »« less

Proton-neutron alignment in the yrast states of {sup 66}Ge and {sup 68}Ge

Hasegawa, M. ; Kaneko, K. ; Mizusaki, T. September 2004 - Physical Review. C, Nuclear Physics

The {sup 66}Ge and {sup 68}Ge 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{sub 9/2} orbit, at high spins (14{sub 1}{sup +}, 16{sub 1}{sup +}, and 18{sub 1}{sup +}) in these N{approx_equal}Z even-even nuclei. It is shown that a series of the even-J positive-parity yrast states (observed up to 26{sub 1}{sup +} for {sup 68}Ge) consists of the ground-state band and successive three bands withmore »« less
