Abstract
We have studied transverse momentum distributions for exclusiveρ 0 muoproduction on protons and heavier nuclei at 2<Q 2<25 GeV2. TheQ 2 dependence of the slopes of thep 2 t andt′ distributions is discussed. The influence of the non-exclusive background is investigated. Thep 2 t -slope for exclusive events is 4.3±0.6±0.7 GeV−2 at largeQ 2. Thep 2 t spectra are much softer than inclusivep 2 t spectra of leading hadrons produced in deep inelastic scattering.
