Abstract：
Various E1 transition rates for cc states are calculated in a QCD-motivated potential model. Relativistic corrections are found to be substantial. A good agreement between theory and experiment is achieved for the rates of ψ(2 S)→YX _eJand X _eJ→γψ(1S) ( J=0,1,2), but the calculated rates for ψ(3770)→YX _eJare smaller by a factor of 2 than their experimental values obtained by the Mark III Collaboration. The effect of the 2 ³ S _l-1 ³ D ₁mixing may be important and needs to be considered.
