Abstract

Thermal neutron capture gamma-ray spectra for ¹⁸⁷Re(n,γ) ¹⁸⁸Re reaction were meaured. Singles and coincidence spectra were detected in order to develop the level scheme. The valuation is in progress, of which the first results are obtained from the analysis of coincidence spectra, allowing to check the level scheme below 500 keV excitation energy. Seven low-energy negative parity bands are developed in order to find better energies for rotational levels. With a good confidence, a few positive parity bands are developed as well. Rotor plus two quasiparticle model calculations, employing effective matrix element method are performed for the system of six negative parity rotational bands.
