Evidence for ground and both neutron and proton rotational aligned bands in 68Ge

From in-beam, γ-ray spectroscopy, the yrast band in 68Ge is found to branch into three positive parity bands at 8 +. Bands built on both the yrast 8 + and second 8 + levels show strong backbending in I while the third is apparently a continuation of the ground band. The two lowest 8 + bands provide...

Description
Summary:From in-beam, γ-ray spectroscopy, the yrast band in 68Ge is found to branch into three positive parity bands at 8 +. Bands built on both the yrast 8 + and second 8 + levels show strong backbending in I while the third is apparently a continuation of the ground band. The two lowest 8 + bands provide the first evidence for both proton and neutron rotation-aligned bands built on the same configuration in the one nucleus, here g 9 2 ) 2 . Rotational aligned model calculations confirm these assignments.
