Popis: | The influence of effective tensor forces on the fission barriers of nuclei in the uranium region has been studied. A modified Fayans energy density functional (EDF) FaNDF0-a, which differs from the initial energy density functional FaNDF0 in the inclusion of strong effective tensor interaction, has been proposed. For the 236U and 238U isotopes, this results in a significant, about 1 MeV, reduction of the first barrier, approaching the values to the known experimental values. However, a noticeable, about the same order of magnitude, difference from these experimental values remains. Possible reasons for this remaining difference are discussed. |
