Abstract

Both the accomplished to date model-free extraction of level density and radiative strength functions of cascade gamma dipole transitions and subsequent model approximation of their parameters have shown the need to develop a new model of compound-state of any masses and types decay. The required model should explicitly take into account the dynamics of the coexistence and interaction of Fermi and Bose forms of nuclear matter. Such a model will almost define thresholds for nucleon pairs breaking gap below the neutron binding energy, the ratio of level density of quasiparticle/phonon type, and the peculiarities of radiative strength functions of gamma transitions in heated nuclei. In general, the state-of-the-art technology of modern experiment has opened an opportunity for much more realistic descriptions of nucleus properties below the giant resonance energy than ones from the statistical theory of the nucleus.
