  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 V-low-k that preserves exactly the two-nucleon
low-energy physics. This V-low-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.
