M ay 1 99 8 Hyperon properties in finite nuclei using realistic Y N interactions


Single-particle energies of Λ and Σ hyperons in several nuclei are obtained from the relevant self–energies. The latter are constructed within the framework of a perturbative many-body approach employing present realistic hyperon-nucleon interactions such as the models of the Jülich and Nijmegen groups. The effects of the non-locality and energy-dependence… (More)
