Nuclear Structure and the Nucleon-Nucleon Interaction

This paper summarizes very briefly the results of some nuclear structure calculations using realistic two-body interactions which fit nucleon-nucleon scattering data. Using realistic interactions, and many-body techniques such as the reference spectrum and an approximate treatment of three-body correlations the binding energy and density of nuclear matter are quantitatively accounted for. Realistic interactions have also been used in Hartree-Fock calculations and results for the ground state of ${\mathrm{O}}^{16}$ are briefly discussed. Finally there are some remarks concerning the effective interaction to be used in shell-model calculations and in particular, the need to include core excitation in order to fit quantitatively the spectrum of two-particle nuclei such as ${\mathrm{O}}^{18}$.
