“…Our study of the 188 Re levels [7] disclosed some problems for interpretation of the level scheme above 400 keV. First, the experimental density of positive parity levels below 1 MeV is about three times higher than predicted by the performed particle plus rotor coupling model (PRC) calculations with the axially-symmetric core deformation.…”

Abstract. Structure of the |K ± 2| bands in doubly-odd nuclei belonging to the transitional deformation region at A∼190 is discussed. Relation of these quasi gamma-bands with the non-axial deformation of the parent twoquasiparticle configurations is studied. Using available experimental information, new tentative |K ± 2| bands are proposed in 188 Re, and 192,194 Ir nuclei. Coexistence of two-quasiparticle states with different deformation modes is considered in the case of 188 Re and 194 Ir.

“…The doubly-odd 186 Re nucleus is a close neighbour to the 188 Re which has been an object of our previous studies [1]. It has been shown that the experimentally established high density of positive parity levels below 1 MeV, as well as properties of some two-quasiparticle configurations indicate coexistence of axially-symmetric and non-axial deformation modes in 188 Re.…”

Abstract. Levels of 186 Re have been studied in the thermal neutron capture reaction with an enriched 185 Re target. Evaluation of spectrum measured with GAMS5 allowed to obtain energies and intensities of more than 500 γ-lines assigned to 186 Re. Most of the obtained transitions have been placed in the model-independent level scheme of the doubly odd 186 Re nucleus, taking into account the available data of earlier experiments as well as the results of recent 187 Re(p, d) 186 Re reaction measurements. Structure of the 186 Re low-lying levels has been analysed in terms of the particle-plus-rotor coupling model.
