Description

Fission barriers for even-even nuclei in the region (Th ... Ku) are calculated in the framework of the Strutinsky method and using the concept of dynamic fission paths. The single particle states are calculated in a deformed Woods-Saxon potential including axial asymmetry at the inner barrier and deviation from reflection symmetry at the outer barrier. It is shown that in the present model also the mass symmetric outer barrier is unstable against axially asymmetric (γ) distortions. (orig.)

Abstract (German)

Im Rahmen der Strutinsky-Theorie wurden mit Hilfe des Konzepts der dynamischen Spaltungswege die Spaltungsschwellen fuer (g,g)-Kerne im Bereich (Th ... Ku) berechnet. Die Einteilchenzustaende werden in einem deformierten Woods-Saxon-Potential mit achsialer Asymmetrie an der inneren Schwelle und einer Abweichung von der Spiegelsymmetrie an der aeusseren Schwelle berechnet. Es wird gezeigt, dass im vorliegenden Modelll auch die massensymmetrische aeussere Schwelle instabil gegenueber achsial asymmetrischen (γ) Stoerungen ist. (orig.)
