Evaluation of fission fragment moments of inertia forspontaneous fission of CF-252

Abstract In the present study, methods for estimating the moments of inertia of fission fragments resulting from the spontaneous fission of isotope Cf-252 were analyzed. In particular, two main approaches were examined: statistical and microscopic. The classical and superfluid approaches for calculating the moments of inertia were also examined, along with their implementations in a variety of nuclear models. In this context, the impact of diverse oscillation modes and nucleon exchange on the moments of inertia and spin distributions of fission fragments was assessed. This study emphasizes the need for a comparative analysis of theoretical predictions and experimental data, which would contribute to a more comprehensive understanding of the internal structure of nuclei and the mechanisms of fission.
