Core of Nucleon-Nucleon Interaction

Abstract

We investigated the argument of Vinh. Mau eta/. [1991] that the good description of the nucleon-nucleon NN interaction at short distances by quark models could be questioned. The quark model is simulated at short distances by a repulsive short range nonlocality. For larger radii, the one pion exchange potential OPEP is used. We found that the quark model alone at the core region can only reproduce the deuteron binding energy, but fitting other NN properties needs high local repulsion.
