Self-consistent nuclear shell-model calculation starting from a realistic NN potential

First self-consistent realistic shell-model calculation for the light p-shell nuclei is performed, starting from the high-precision nucleon-nucleon (NN) CD-Bonn potential. This realistic potential is renormalized deriving a low-momentum NN potential Vlow-k that preserves exactly the two-nucleon low-energy physics. This Vlow-k is suitable to derive a self-consistent Hartree-Fock basis that is employed to derive both effective single-particle energies and residual two-body matrix elements for the shell-model Hamiltonian. Results obtained show the reliability of such a fundamental microscopic approach.
