摘要
We present a consistent framework for treating the energy and angular momentum dependence of the nuclear shape evolution in the fission process. It combines microscopically calculated level densities with the Metropolis walk method and it contains no new parameters. The treatment can elucidate the influence on the shape dynamics of warm nuclei of pairing and shell effects as a function of the excitation energy.
