Exclusive 0 and muoproduction on deuterium, carbon and calcium has been studied in the kinematic range 2 < Q 2 < 25 GeV 2 and 40 < < 180 GeV . We discuss the Q 2 dependence of the cross sections, the transverse momentum distributions for the vector mesons, the decay angular distributions and, in the case of the 0 , n uclear eects. The data for 0 production are compatible with a diractive mechanism. The distinct features of production are a smaller cross section and less steep p 2 t
