Description

A comparison between the semi-classical approximation and the full quantum calculation with a complex absorbing potential is made with a model of the fission of 258Fm. The potential barrier is obtained with the constrained Skyrme HF+BCS theory. The life-time obtained by the two calculations agree with each other, the difference being only 25% approximately. This difference could be attributed to the assumption of 'harmonicity' for the confining potential or to the accuracy of the semi-classical approximation. (authors)
