Abstract
Experimental evidence for the diffractive production of Ψ mesons in weak neutral current reactions is reported. The spectrum-averaged cross section for this process is σdiff = (4.2±1.5) × 10-41 cm2/nucleon, in agreement with gluonfusion models, but at variance with vector dominance calculations.
