Abstract:
The purpose of this work is the study of non-equilibrium high-energy gamma emission from 252Cf. In the framework of the formalism of statistical multi-step compound processes in nuclear reactions a relation was found between the shape of the high-energy part of the gamma spectrum and diffent mechanisms of excitation of the fission fragments. Agreement with experimental data for different groups of fission fragments was obtained. The analysis of the experimental high-energy part of gamma spectra yields information about the mechanism of excitation of fission fragments. The influence of dissipation of the deformation excess on intrinsic excitation of fission fragments was studied.
