Abstract
We have studied transverse momentum distributions for exclusive ρ0 muoproduction on protons and heavier nuclei at 2<Q2<25 GeV2. The Q2 dependence of the slopes of the pt2 and t′ distributions is discussed. The influence of the non-exclusive background is investigated. The pt2-slope for exclusive events is 4.3±0.6±0.7 GeV-2 at large Q2. The pt2 spectra are much softer than inclusive pt2 spectra of leading hadrons produced in deep inelastic scattering.
