Abstract

The near-stable nucleus ¹⁸⁴₇₅Re has been studied using the ¹⁸⁰Hf(⁷Li, 3n)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 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.
