Nuclear-Matter Calculations Using a Realistic Nucleon-Nucleon Potential

A realistic nucleon-nucleon potential is used to formulate a simple Thomas-Fermi method for nuclear-structure calculations. The potential-energy density has only one free parameter, which is found by fitting with Bhargava and Sprung's calculation. The short-range repulsion is absorbed in the term containing the free parameter. The compressibility comes out to be good. We illustrate our method in nuclear matter only with ${}_{}{}^1{}_{}{}^{}S$ and ${}_{}{}^3{}_{}{}^{}S$ states, although the method is applicable in the general case.
