Abstract

We have studied some of the bulk and microscopic properties of symmetric nuclear matter within Bruckner-Hartree-Fock approach with angle average approximation and exact Pauli operator using different nucleon-nucleon potentials. The considered potentials in this study are A V18 and Nijm I potentials, which give different equations of state. We focused in this work on the influence of Pauli operator treatment on the nuclear matter properties. Our results are good compared with previous studies. However, the empirical saturation point was not achieved. To refine the results, additional approximations were required. Remarkably, introducing three-body forces into the equation of state, particularly using the A V18 potential, produced outcomes that closely matched empirical data. Another approach involved adding a correction term to the two-body force, which also resulted in values consistent with empirical observations.
