Contribution

It introduces a method to incorporate three-body effects into the nuclear EOS calculations with improved agreement to empirical data.

Findings

Good agreement with exact calculations including three-body forces

Effective two-body density dependent potential reproduces empirical saturation point

Enhanced understanding of three-body force effects on nuclear matter properties

Abstract

Three body effects are studied for both asymmetric nuclear matter and pure neutron matter to calculate the nuclear Equation of State . The Brueckner Hartree Fock approximation is used using CD Bonn B and Argonne V18 potentials. A two body density dependent Skyrme potential is added to reproduce the empirical saturation point. Good agreement is obtained in comparison with exact calculation including three body forces.
