Abstract

By utilizing the screened potential model, the spectra and decay properties of hydrogen-like mesons (QqBAR) are studied. The calculated ratio of M1 decay widths for the D+ and D*0 mesons is 0.0286. This result is much smaller than the data of MARK3 in 1988, but agrees with the observed data of CLEO in 1992. The result indicates that the contradiction between the calculated result and the data of MARK3 for hydrogen-like mesons in the quark model can be understood, if future experimentcan confirm the data of CLEO in 1992.
