Abstract

Excited levels of ¹⁸⁶Re have been studied using results of the single γ-ray spectra measurements following the thermal neutron capture reaction. Energies and intensities of more than 500 γ-transitions have been obtained with the high-resolution crystal diffraction spectrometer GAMS5 of ILL. Most of the obtained intense γ-transitions have been placed in the ¹⁸⁶Re level scheme. A number of new levels, as well as the depopulation for levels observed earlier in the ¹⁸⁷Re(p,d)¹⁸⁶Re reaction measurements have been proposed. Structure of ¹⁸⁶Re levels is interpreted in terms of two-quasiparticle plus rotor coupling model and compared with that of the neighbouring doubly-odd nucleus ¹⁸⁸Re.
