Abstract

Exclusive ρ{variant}0 and φ muoproduction on deuterium, carbon and calcium has been studied in the kinematic range 2< Q2< 25 GeV2 and 40 < ν < 180GeV. We discuss the Q2 dependence of the cross sections, the transverse momentum distributions for the vector mesons, the decay angular distributions and, in the case of the ρ{variant}0, nuclear effects. The data for 0 production are compatible with a diffractive mechanism. The distinct features of φ production are a smaller cross section and less steep pt2 distributions than those for the 0 mesons.
