Query: Nuclear Matter Equation of State and Three body Forces   The energy per particle, symmetry energy, pressure, Free energy are
calculated for asymmetric nuclear matter using BHF approach and modern
nucleon-nucleon CD-Bonn, Nijm1, Argonnev18 and Reid93 potentials. To obtain
saturation in nuclear matter we add three-body interaction terms which are
equivalent a la Skyrme to a density-dependent two-nucleon interaction. Good
agreement is obtained in comparison with previous theoretical estimates and
experimental data.
