Show affiliationsA generalized finite-range liquid-drop model based on the Yukawa-plus-exponential potential was applied to describe fission dynamics of hot rotating nuclei. The potential energy, level-density parameter and Helmholtz free energy are calculated in a consistent way by using the generalized finite-range liquid-drop model. The level-density parameter was approximated by a leptodermous-type expression. The coefficients of this expansion are in surprisingly good agreement with those obtained earlier by Ignatyuk and co-workers. The results of Langevin dynamical calculations of the mean prescission neutron multiplicity and fission probability are practically the same both for the level-density parameter calculated with Ignatyuk's coefficients and the one calculated using the generalized finite-range liquid-drop model. This fact lets us assume that all previous results of dynamical Langevin calculations performed with Ignatyuk's level-density parameter stay reliable.
