| contents | This paper discusses modern methods for estimating the moments of inertia of fragments formed during forced fission of the isotopes 232Th(n,f) and 238U(n,f). The study analyzes two fundamental approaches -- statistical and microscopic. Special attention is given to their implementation within both classical and superfluid models, enabling a more detailed description of nuclear dynamics during fission. Various physical factors influencing the calculation of moments of inertia are examined, including transverse vibrational modes and nucleon exchange mechanisms. These effects significantly impact spin distributions and the interpretation of experimental data. The analysis also addresses the role of nuclear models that vary with fragment deformation, allowing key regularities in internal structure to be identified. Emphasis is placed on comparing theoretical predictions with experimental results, which remain essential for model validation. This approach not only deepens understanding of fission mechanisms but also supports the broader study of fundamental nuclear properties. |
