Phenomenological model of fission barriers of hot rotating nuclei

  • Published:
Zeitschrift für Physik A Hadrons and Nuclei

Abstract

Fission barriers, level densities, mass and friction parameters of hot rotating nuclei along the fission path are calculated in a multidimensional deformation space. The shape parameterization of Trentalange, Koonin and Sierk is used in order to test higher multipole effects on the collective potential, moment of inertia, collective mass and friction coefficient which enter a dynamical description of the fission process in terms of a unique collective variable. The dependence of the level density parametera on mass number, neutron excess and deformation is analyzed. All calculations are performed for medium-mass to heavy nuclei.
