Abstract

We investigated the argument of recent publications that the good description of the nucleon-nucleon interaction at short distances by quark models is at present only qualitative. The quark model is simulated at short distances by a repulsive short range nonlocality. For larger radii, the one pion exchange potential is used. We found that the quark model alone at the core region can only reproduce the deuteron binding energy, but fitting other nucleon-nucleon properties needs high local repulsion.
