A self consistent Thomas Fermi calculation of fission barriers at finite temperature and angular momentum as applied to the205At

A two dimensional, self consistent Thomas Fermi calculation of fission barriers, adapted to rotating nuclei at finite temperatures, is described. The Thomas-Fermi equations, applied to the²⁰⁵At nucleus, are solved by a procedure analogous to that adopted in solving constrained Hartree-Fock equations. It is shown that the computed fission barrier decreases with increasing temperature and angular momentum.
