Abstract The equation of state for nuclear matter is presented within the Brueckner–Hartree–Fock (BHF) scheme, by using the realistic Argonne V18 or Bonn B two-nucleon potentials plus their corresponding microscopic three-nucleon forces. It is then applied to calculate the properties of finite nuclei within a simple liquid-drop model, and we compare the calculated volume, surface, and Coulomb parameters with the empirical ones from the liquid drop model. Nuclear density distributions and charge radii in good agreement with the experimental data are obtained, and we predict the neutron skin thickness of various nuclei.
