Nuclear Potential and Symmetry Energy

A quadratic dependence on momentum is assumed for the two-nucleon interaction energy in the independentparticle model, and is used in a study of the nuclear binding energy and symmetry energy. The corresponding optical potentials for elastic nucleon scattering are discussed. The semiempirical interaction used is compared with the two-body potentials commonly used in shellmodel calculations. These are found to be inadequate. (auth)
