| Abstract: | A phenomenological estimate is derived such that the binding energies of dimesons are expressed as combinations of masses
of different mesons and baryons. The estimate is almost model-independent, the only major assumptions being that the wave
functions of the two light quarks in Λ

and in the and dimesons are very similar, and that for heavy quarks the QQ interaction is half as strong as the interaction. We get (I = 0, J = 1) bound by about 100 MeV and unbound.
