摘要：
J/psi coherent production and attenuation on nuclei by high energy muons and photons is studied. A simple one-parameter model leads to a good description of the New Muon Collaboration and Fermilab data. It is found that the effective absorption cross section of the ccBAR pair on a target nucleon is about 6 mb.
