A modified Kramers approach to describing the fission of excited atomic nuclei

We present a detailed comparison of the analytical Kramers fission rate (KFR) and the dynamic quasi-stationary rate (QSFR) obtained by numerical simulation. It turns out that for the polynomial potential, the KFR regularly exceeds the QSFR by more than 5%. We obtain KFR corrections that allow us to...

Description
Summary:We present a detailed comparison of the analytical Kramers fission rate (KFR) and the dynamic quasi-stationary rate (QSFR) obtained by numerical simulation. It turns out that for the polynomial potential, the KFR regularly exceeds the QSFR by more than 5%. We obtain KFR corrections that allow us to reduce this disparity to 1%.
