Forward photoproduction of rho /sup -/ mesons on nuclei

Forward photoproduction of rho -mesons on nuclei Al, Be, C, Cu at the incident gamma -quanta energy up to 4.5 GeV is investigated using a two-shoulder spectrometer.

Sumario:Forward photoproduction of rho -mesons on nuclei Al, Be, C, Cu at the incident gamma -quanta energy up to 4.5 GeV is investigated using a two-shoulder spectrometer. Individual channels to the production reactions were not separated. The experiment was modelled by means of the Monte-Carlo method using the standard routine FOWL (CERN) modernized to speed the computations. It is found that (d sigma /dt) /sub forw/ approximately A/sup 0.83/. This fact does not agree with predictions of the Glauber approach, applied to the noncoherent process. (15 refs).
