Abstract
The level density of the odd-odd nucleus Pr-132 is investigated in the interacting boson-fermion-fermion model (IBFFM) which accounts for co llectivity and complex interaction between quasiparticle and collectiv e modes. The IBFFM total level density is fitted by a Gaussian and its tail is also fitted by Bethe formula and constant temperature Fermi g as model. The IBFFM spin-dependent level densities show high-spin redu ctions with respect to Bethe formula. This can be well accounted for b y a modified spin-dependent level density formula.
