Abstract
The change in the octupole deformation of nuclei in the chain of even–even radium isotopes is studied on the basis of the Hartree–Fock–Bogoliubov method with an effective Skyrme interaction. Nucleon pairing is described in terms of density-dependent zero-range pairing forces of mixed type. Conditions imposed on the quadrupole and octupole moments of nuclei were used in respective calculations. The dependence of the calculated features of nuclei on the choice of pairing forces is studied. The calculations show that there is a strong dependence of the octupole deformation of nuclei on the choice of parameters of nucleon-pairing forces.
