✦ Synopsis

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 molecular 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), ψ(4.040) etc are identified as the low lying di-mesonic states, and Θ + (1.54) as a K -N molecular state.
