摘要：

Using power law potential as an effective potential, the fine structure of mass spectrum of QQ and Qq system is examined. We find the masses of D* and D within 20 MeV of their experimental values. We predict the masses of DJ = 2, 1, 0 to be 2.47, 2.44, and 2.30 GeV and that of D′J = 1, to be 2.36 GeV. For DsJ = 2, 1, 0 and D′sJ = 1, we obtain the values for their masses of 2.57, 2.55, 2.42, and 2.48 GeV. We also calculate |ψ1s(0)|2 for QQ and Qq systems. We find fD = 220 MeV and fB = 143 MeV with the normalization that fn = 93. © 1992.
