ABSTRACT

A formation of a highly-excited nucleus with a large lifetime after the completion of the INC is an important result of investigations of the energy dissipation in a deep inelastic interaction. An equilibrium statistical model based on the concept that a compound nucleus (C-nucleus) does exist is used, as a rule, in such investigations. Large values of the excitation energy of C-nuclei introduce their specific features into the substantiation of the model. The density of nuclear levels and the cross-section of the inverse reaction are basic quantities in the statistical description of the decay. Density of nuclear levels is an important characteristic lying in the basis of the statistical model of decay of a C-nucleus. For high values of the excitation energy, single-particle degrees of freedom of a nucleus must dominate, since the number of collective modes is small compared to the total number of degrees of freedom of its constituent particles.
