摘要
Spontaneous fission barriers, quadrupole inertia tensor, and zero-point quadrupole correlation energy are calculated for Fm-252,Fm-256,Fm-258 in the framework of the self-consistent Skyrme-Haxtree-Fock+BCS theory. Two ways of computing collective inertia are employed: the Gaussian Overlap Approximation to the Generator Coordinate Method and cranking ansatz. The Skyrme results are compared with those of the Gogny-HartreeFock-Bogolyubov model.
