Abstract:

Exclusive OZI violating radiative decays of heavy 1^-- vector mesons into heavy 0^-+ pseudoscalar mesons are considered in QCD. Using the lowest order perturbation the decay widths are given. For Ψ→η^′+ γ our calculation leads to consistent result. Some predictions for other decays are presented.
