Possibilities of determining the main peculiarities of {gamma}-decay cascades in heavy nuclei

Abstract

The main results of an analysis of the average parameters for {gamma} -decay cascades of compound states in complex nuclei are presented. The experimental data of nuclear level densities, for certain J{sup {Pi}}, at excitation energies above 2 MeV are compared with that predicted by two different theoretical modes. Cascade intensities measured over the entire excitation energy range, from the ground state up to the neutron binding energy, are compared with different model predictions. Conclusion about the radiative partial width enhancements for transitions between the compound state and high lying excited states are given. The problems of estimating the actual temperature of excited nuclei, and of the experimental possibilities to observe phase transitions and their influence on {gamma} - decay modes are discussed. (author.). 18 refs.; 12 figs.; 2 tabs.
