QUASI-ELASTIC J PSI MUOPRODUCTION FROM HYDROGEN, DEUTERIUM, CARBON AND TIN/

Quasielastic production of J/psi mesons has been measured in muon inte ractions with hydrogen, deuterium, carbon and tin targets at incident muon energies of 200 and 280 GeV. The hydrogen and deuterium data were used to study the transverse momentum distribution of the J/psi's. Th ese data have been analysed together with previously published rho0 da ta in the framework of the vector meson dominance model. The radii of the J/psi and the rho0 as well as the total J/psi-N and rho0-N cross s ections were deduced. From the tin and carbon data the ratio of the qu asielastic J/psi production cross sections, R(qe)(Sn/C), has been extr acted and found to be less than unity. In the Glauber approach this su ppression can be related to the J/psi absorption probability in nuclei . The suppression is also compared to those predicted by various colou r transparency models.
