| Abstract: | Considering ψ (4030) as a semi stable bound state of D*D* instead of exitedstate of J/ψ, the spectra of the J/ψ family can de described by the wave equation of har-monic oscillator with mass squared eigen values. The case is similar with that of the or-dinary mesons. The only difference is that the gap of energy level squared for J/ψfamily is as twice large as the ordinary hadrons. The similar conclusion is also valid tothe γ family with energy level gap 5.6 times larger than the ordinary hadrons. In edition, the mixing of S and D wave induced by tensor force is calculated and the energylevel of ψ(3770) with D wave dominance is obtained. |
