Ground-state properties of closed-shell nucleus {sup 56}Ni with realistic nucleon-nucleon interactions
We have calculated the ground-state energy of the doubly magic nucleus {sup 56}Ni within the framework of the Green's function using the CD-Bonn and N{sup 3}LO nucleon-nucleon potentials. For the sake of comparison, the same calculations are performed using the Brueckner-Hartree-Fock approximation. Both the continuous and conventional choices of single particle energies are used. Additional binding energy is obtained from the inclusion of the hole-hole scattering term within the framework of the Green function approach. In this study, comparison of the calculated ground-state energies, obtained by using the Brueckner-Hartree-Fock approach using continuous choice and different nucleon-nucleon potentials, with the experimental value is accomplished. The results show good agreement between the calculated values and the experimental one for the {sup 56}Ni nucleus. The sensitivity of our results to the choice of the model space is examined.
