Abstract

The potential energy surface of 240Pu has been investigated in the framework of the relativistic mean field theory. The self-consistent field equations were solved numerically on an axially symmetric grid in the coordinate space with the addition of a quadrupole constraint. The double humped fission barrier typical for 240Pu is well reproduced by the model. We discuss the influence of the different parametrizations of the model on the deformed ground state, the first barrier, the deformed isomeric state and the second barrier.
