【正】 The ground-state(GS)binding energies of the■hyperon in a few known■hyper-nuclei are calculated by solving Schr■dinger and Dirac equations with phenomenological■nu-cleus potential of Woods-Saxon shape.The calculated binding energies are in good agreementwith the experimental values.The optimal well depth of■-nucleus potential is extracted:U■=23.9 MeV.
