FOLDING POTENTIAL OF THE QUARK CLUSTER AND n-p SYSTEM

According to the quark model of hadron, the nucleon is composed of quarks with strong interactions between themselves. We regard the nucleon as cluster of quarks and assume that the nuclear force is given by the folding potential between the clusters. In this paper we shall explore the connexion between the nuclear force and the interaction of quarks, and calculate the n-p system from this point of view.
