摘要：

Multiquark systems such as tetraquarks, pentaquarks and hexaquarks states are studied as di-hadronic molecules in a nonrelativistic model. The masses of several di-hadronic states using a molocular interaction provided by asymptotic expression of the confined gluon exchange potential are computed. The exotic states such as f(0) (0.982), f(2) (1.565), f(2) (1.950), X(3.87) D-sJ (2.317, 2.460, 2.632) psi(4.040) etc are identified as the low lying di-mesonic states, and circle minus(+) (1.54) as a K-N molecular state.
