Abstract

Mechanism of reduction of (static) fission-barrier height B{sup st}{sub f} by non-axial deformations is studied for the nucleus {sup 250}Cf. Two-dimensional (quadrupole) deformation space is used. It is found that the reduction is the effect of a rather strong change of shell structure with a change of deformation of the nucleus. (author)
