Abstract (data abstract)
DESY-HERA. Measurements of single and double differential cross sections for leptoproduction of J/PSI mesons in collisions of beams of 27.5 Gev positrons (88%) and electrons (12%) with 820 Gev and 920 GeV protons. The data were taken during the 1997 to 2000 HERA running period with a total luminosity of 77 +- 1.2 pb-1 (63 pb-1 were with 920 GeV protons).. The rapidity distribution (YRAP) is shown w.r.t the proton direction in the laboratory frame and w.r.t. the photon direction in the photon-proton centre-of-mass frame.. The transverse momentum distributions (PT**2) are shown w.r.t the beam axis in the laboratory frame and also in the GAMMA* P centre-of-mass frame.
