DESY-HERA. Measurement of the inelastic J/PSI and PSIPRIME photoproduction cross sections from the interactions of 27.5 GeV electrons and positrons with 920 (820) GeV protons corresponding to a centre-of-mass energy of 318 (300) GeV. The data were collected during the 1998-2007 (1996-1997) running periods with total integrated luminosity of 430 (38) pb-1. The ratio of J/PSI to PSIPRIME are measured in the Z range 0.55-0.9 and W range 60-190 GeV and the J/PSI cross section in the Z range 0.1-0.9 and W range 60- 240 GEV with PT > 1 GeV.
Measured J/PSI differential photoproduction cross section as a function of PT^2 in the Z range 0.30-0.45.
