Skyrme Hartree-Fock, single particle energies, double magic nucleus 78 Ni
Abstract :
[en] We calculate the single particle spectrum of the double magic nucleus $^{78}$Ni
in a Hartree-Fock approach using the Skyrme density-dependent effective interaction
containing central, spin-orbit and tensor parts.
We show that the tensor part has an important effect
on the spin-orbit splitting of the proton $1f$ orbit which may explain the survival of magicity
so far from the stability valley. We confirm the inversion of the $1f5/2$ and $2p3/2$
levels at the neutron number 48 in the Ni isotopic chain expected from
previous Monte Carlo shell model calculations and supported by experimental observation.
