Short-range correlations and pseudopotentials. V

Abstract

Deformed Hartree-Fock-Bogoliubov calculations have been carried out with an effective interaction derived from the different Hamada-Johnson, Yale, Tabakin, and Reid potentials and from the potential $A$ calculated by us. Short-range pseudopotentials are introduced to these potentials to achieve healing in the correlated wave functions and to produce zero-phase shift in the pair state. The deformed Hartree-Fock-Bogoliubov method has been applied to the $2p\ensuremath{-}1f$ shell even-even nuclei. Intrinsic quadrupole moments $〈Q_{0}^{}{}_{}{}^{2}〉$, quadrupole moments of the first excited states ${Q}_{2+}$, and the reduced transition probabilities $B(E2) ({0}^{+}\ensuremath{\rightarrow}{2}^{+})$ have been calculated. The angular momentum projected spectra for these nuclei have also been obtained. The present calculations of quadrupole moments, transition probabilities, and angular momentum spectra for the different Ti, Cr, Fe, and Ni isotopes are in good agreement with the experimental results.NUCLEAR STRUCTURE $^{44,46,48,50}\mathrm{Ti}$, $^{48,50,52,54}\mathrm{Cr}$, $^{52,54,56,58}\mathrm{Fe}$, $^{58,60,62,64}\mathrm{Ni}$; calculated intrinsic quadrupole moments, quadrupole moments of the first excited states, reduced transition probabilities, projected angular momentum spectra and energy levels; pseudopotentials.
