摘　　要：We study charmonium （ccnn）,bottomonium （b bnn） and exotic （ccnn and bbnn） four-quark states by means of a standard non-relativistic quark potential model.We look for possible bound states.Among them we are able to distinguish between meson-meson molecules and compact four-quark states.We study charmonium （ccnn）,bottomonium （b bnn） and exotic （ccnn and bbnn） four-quark states by means of a standard non-relativistic quark potential model.We look for possible bound states.Among them we are able to distinguish between meson-meson molecules and compact four-quark states.
