Query: Mass spectra of meson molecular states for heavy and light sectors   We obtain mass spectra of the light and heavy meson-antimeson (molecular
states) sectors by using a nonrelativistic potential model with Coulomb and one
pion exchange potential terms for meson-meson interaction. The digamma decay
widths are also obtained for the light sector. We compare our results with
available experimental and theoretical data.
