Quark aspects of nuclear forces

Within the framework of the nonrelativistic approach with account of baryon quark freedom degrees some aspects of the problem of nuclear forces are discussed. In this approach the interbaryon forces arise as a result of averaging of interaction between quarks from different baryons on quark motion inside the baryons and conform to the quark exchange between baryons. In conformity with the problem discussed the resonating-group method is outlined in brief. The behaviour of effective NN-interaction at short distances is considered in detail. It is noted that effective NN potential possesses a soft repulsion core and that this repulsion is caused by qq interaction
