Abstract

By using the self-consistent approach based on the Skyrme functional and with account of pairing correlations, we calculate global properties of nuclei, such as binding energies, one and two-neutron separation energies, density distributions of nucleons, root-mean-square radii of nucleon distributions. For description of excitation energies and transition rates we apply the RPA+BCS approach based on the finite range effective interaction defined by us before. Everywhere, where it is possible, we perform comparison of theoretical results with the experimental data.

Highlights

Study of evolution of nuclear properties in the long chains of isotopes or isotones, from the extremely protonexcess up to the extremely neutron-excess nuclei is of special theoretical interest, as here one can check the adequacy of the used theoretical models in the broad interval of (N − Z)/A
Different long chain is represented by the sequence of the nickel isotopes from 48Ni up to 78Ni, where all nuclei, except for 78Ni, turn out to be discovered by the present time
The mentioned chain is of special interest as it includes doubly-magical nucleus 48Ni, and 78Ni

Summary

Introduction

Study of evolution of nuclear properties in the long chains of isotopes or isotones, from the extremely protonexcess up to the extremely neutron-excess nuclei is of special theoretical interest, as here one can check the adequacy of the used theoretical models in the broad interval of (N − Z)/A. For description of global properties of nuclei such as their masses, root-mean-square radii of nucleon distributions, one- and two-nucleon separation energies, as well as single-particle energies of protons and neutrons, we apply the Hartree–Fock+BCS method.
