Realistic calculations of parity distributions and densities of exciton states at high excitation energy

The density of states with fixed number of excitons and parity distribution in even-even nuclei has been studied as a function of excitation energy. In the calculations the properties of thermodynamic systems of even-even nuclei with realistic sets of single particle states and pairing constants has been used. The transformation of properties of even-even into odd thermodynamic system is also discussed. (orig.)
