The odd-odd nuclei are characterized by a level density which is high already in the low-energy region. This case displays a full complexity of the interwoven shell-model and collective degrees of freedom and thus provides an interesting testing ground for the pattern of nuclear level density. The level density of the odd-odd nucleus 196Au is investigated in the interacting boson-fermion-fermion model which accounts for collectivity and complex interaction between quasiparticle and collective modes. In the present work, the IBFFM pattern of total and parametric dependent level densities is investigated and compared to the pattern found in previous investigations in the framework of combinatorial, thermodynamic and spectral distribution approaches.
