Abstract The elastic Jpsi cross section is measured in the kinematic region Q2 <1 GeV^2, 40 < W < 150 GeV and |t| < 1.2 GeV^2 using the decay channel J/psi -> mu^= mu^-. The analysis is based on an integrated luminosity of 54.8 pb^-1. Single and double differential cross sections are measured as a function of W and |t| and are compared to calculations in perturbative QCD.
