It revisits the inconsistency issue by examining the features of individual trajectories on the fission path, providing new insights into the theoretical conflict.

Findings

Identifies key differences between the two models' predictions.

Provides a trajectory-based perspective on the inconsistency.

Suggests potential resolutions or clarifications for the theoretical conflict.

Abstract

The problem of an apparent inconsistency between the fission rates derived on the basis of Bohr-Wheeler's transition-state method and Kramers' dynamical model of nuclear fission, first pointed out by Strutinsky in 1973, is revisited. The study is based on studying the features of individual trajectories on the fission path.
