摘要：

Excited states in 175Re have been identified using the Dy-161(F-19, 5n)175Re reaction and gamma-ray spectroscopy. Rotational bands associated with the 1-quasiparticle orbitals h9/2, h11/2, i13/2, d5/2 and g7/2 have been identified, most to high-spin. Relative transition rates were used to extract B(M1)/B(E2) ratios and g(K) - g(R) values which support the assignments. Different alignment gains are observed in each of the 1-quasiparticle bands, attributable, at least in part, to configuration-dependent deformation differences. The complex alignment gain observed in the h11/2 band is analysed in a 3-band model. A 3-quasiparticle, isomeric state and its rotational band were also observed. The properties of this band suggest a 1-quasiproton-2-quasineutron configuration for the isomer.
