The Nuclear Potential-energy Surface with Inclusion of Axial Asymmetry

Abstract

The nuclear potential-energy surface has been calculated on the basis of the modified oscillator model, including the degree of freedom of axial asymmetry. The regions investigated are the prolate-oblate transitional region around Os-Pt, the actinide region and the region of superheavy elements. The theoretical results indicate that the first barrier of the two-peak barrier in the actinides is reduced due to axial asymmetry, which leads to an improved agreement with empirical data. There also appears to be a modest reduction of the barrier for superheavy elements.
