Calculating the Octupole Deformation of Radium and Thorium Isotopes in a Hartree–Fock–Bogolyubov Approximation with Skryme Forces

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

A Hartree–Fock–Bogolyubov approximation with Skyrme forces is used to estimate properties of Ra and Th isotopes with A = 218–230 and A = 280–290. The effect of pairing forces is estimated from values of the parameters of quadrupole and octupole nuclear deformation. The pairing of nucleons in nuclei is described by zero-range pairing forces. It is shown that the octupole deformation of nuclei depends strongly on the choice of parameters of the nucleon pairing force.
