摘要

<正> High-spin states in 169Re have been investigated by means of in-beam 7-ray spectroscopy techniques with the 144Sm(28Si, 1p2n) 169Re reaction. X-γ and γ-γ-t coincidences, 7-ray anisotropies, and DCO ratios were measured. A strongly coupled band based on the 9/2-[514] Nilsson state and a decoupled band built on the h9/2 intruder proton orbital (nominally 1/2- [541]) have been established. The AB neutron crossings are observed at hω=0.23 and 0.27 MeV for the 9/2-[514] and 1/2-[541] bands, respectively. The difference between the
