摘要：

The fission dynamics of excited nuclei is studied in the framework of the Langevin equation. One-body wall-and-window friction is used as the dissipative force in the Langevin equation. In addition to the usual wall formula friction, the chaos-weighted wall formula developed earlier is also considered hen. The fission rate calculated with the chaos-weighted wall formula is found to be larger by about a factor of 2 compared to that obtained with the usual wall friction. The systematic dependence of the calculated fission width on temperature and spin of the fissioning nucleus is investigated and a simple parametric form of the fission width is obtained.
