Abstract: The influence for various parameterizations of the nuclear part of the interaction potential to the mass yields of fission fragments of highly excited nuclei for the reaction α+¹⁹⁷Au → fission was studied. It is shown that using of various nuclear potentials leads to small changes in the yields of fission fragments of the nuclei.

Keywords: nuclear interaction, parameterizations of the nuclear part of the interaction potential, nuclei fission, mass yields of fragments from fission.
