| 摘 要： | The newly observed D*sJ family containing D*sJ(2317), DsJ(2460), and DsJ(2632) attracts great interests.Determining their structures may be an important task for both theorists and experimentalists. In this work we use a non-relativistic model (the harmonic oscillator model) to evaluate the production rate of D*sJ (2317) from the decays of ψ(4415). For a comparison, we also employ the widely adopted heavy quark effective theory to repeat the calculation.We find that the rate is sizable and may be observed at BES Ⅲ and CLEO, if it is a p-wave excited state of Ds (1968).Unfortunately, the other two members of the family cannot be observed through decays of charmonia, because of the constraints from the final state phase space.
