Nichtlokale Potentiale im Einteilchen-Modell des Atomkerns

Abstract

In the nonlocal part of the single particle potential of bound nucleons the Gaussian nonlocality, which was used in earlier papers, is replaced by a Yukawa- and an exponential potential. The nonlocal parameters are fitted to the nucleon scattering experiments and the results are used for a calculation of single particle levels of Pb²⁰⁹ and Pb²⁰⁷. The nonlocality required by the Pauli-exclusion-principle is compared with the phenomenological approach. It turns out that the form of this nonlocality is essentially given by the supposed nucleon-nucleon potential. The range of this potential is determined by the experimentally known energy-dependence of the single particle potential.
