| Abstract: | Brueckner and others have applied an extension of the self-consistent method of Hartree-Fock to the determination of the properties of a hypothetical nuclear matter consisting of roughly equal numbers of neutrons and protons, the electrical forces between protons being “turned off”. Taking the nucleon-nucleon interaction potentials to be those of Gammel and Thaler, we have applied the well-known Wigner-Seitz method for crystal lattices to a quasi-lattice model of nuclear matter. This method gives the energy of the lowest single particle state as a function of the internucleonic separation. Good agreement is obtained with the experimental values for the nuclear density and binding energy per nucleon. |
