Spin-dependent level density in interacting boson-fermion-fermion model

The level density of odd-odd nucleus 132 Pr is investigated in the interacting boson fermion fermion model (IBFFM) which accounts for collectivity and complex interaction between quasiparticle and collective modes. The IBFFM total level density is fitted by a Gaussian and its tail is also fitted by Bethe formula and constant temperature Fermi gas model. The IBFFM spin-dependent level densities show high-spin reductions with respect to Bethe formula. This can be well accounted for by our new spin-dependent level density formula.
