FISSION BARRIERS OF SUPERHEAVY NUCLEI

Abstract. The aim of this paper is to give an overview of theoretical predictions on heights of fission barriers for superheavy nuclei. The macroscopic-microscopic model of the potential energy as a function of nuclear shape is briefly presented. Immersion method of searching for saddle points determining the barrier heights which has been recently adapted to nuclear physics is discussed. Predictions of fission barrier heights for a wide region of superheavy nuclei are given, as well as a comparison to results obtained by other approaches and to existing experimental data. I
