摘要：

We develop a rigorous quantum-mechanical treatment of color transparency effects in diffractive photoproduction of ccBAR pairs on nuclei. The evolution of the ccBAR wave function during propagation through a nucleus is more a considerable distortion of its form than a trivial attenuation. One of the manifestations of the quantum effects is a nuclear antishadowing of the psi' yield, i.e., transparency above one. However, considerable nuclear shadowing is predicted for the photoproduction of J/psi, which has a much smaller absorption cross section than psi'.
