Estimating fission-barrier height by the spherical-basis method

Koura, Hiroyuki

A new method of estimating fission barrier heights is presented. Potential energy surface is calculated with the spherical-basis method, which is based on construction of the KTUY mass formula. Under a restriction of symmetric fission, some higher (neighboring $^{252}$ Fm) and lower (neighboring $^{278}$ Ds) fission barrier regions are found, and the origin of these appearances is discussed in the framework of the spherical-basis method. Systematical properties of fission barrier heights are studied in the unknown neutron-deficient superheavy nuclear mass region, where the nuclear fission governs the limit of existence of nuclei.
