摘要：

Positions of the proton and neutron drip lines and characteristics of the neutron-deficient and neutron-rich Fe and Ni isotopes have been studied by the Hartree-Fock method with the Skyrme forces (Ska, SkM*, Sly4) with allowance for deformation. Pairing was taken into account on the basis of the BCS approximation with the pairing constant G = (19.5/2)[1 ± 0.51(N − Z)/A]. Manifestation of magic numbers for the nickel isotopes 48Ni, 56Ni, and 78Ni and for the nucleon-stable isotope 110Ni which is beyond the drip line is discussed.
