Gamma-ray spectroscopy of the doubly-odd nuclide 184Re

The near-stable nucleus 184 75Re has been studied using the 180Hf( 7Li, 3 n) 184Re reaction at 30 MeV. Prior to this work, a number of low-spin structures were known following transfer reaction experiments, but only three γ-ray transitions had been observed following the decay of a t 1 / 2 = 169 day...

Description
Summary:The near-stable nucleus 184 75Re has been studied using the 180Hf( 7Li, 3 n) 184Re reaction at 30 MeV. Prior to this work, a number of low-spin structures were known following transfer reaction experiments, but only three γ-ray transitions had been observed following the decay of a t 1 / 2 = 169 day, 8 ( + ) state. An extensive level scheme has been constructed from the present data, including states de-exciting through the K π = 8 ( + ) isomer and the K π = 8 ( + ) rotational band. Configurations are assigned with the aid of g K − g R values and the comparison of energies with predictions of blocked BCS calculations. Finally, residual nucleon–nucleon interactions for orbitals in this region are collated.
