Abstract
Based on a prior determination of the $Ï$ selfenergy in a nuclear medium we perform a theoretical study of inclusive $Ï$ photoproduction in nuclei, looking at the $A$ dependence of the cross sections for different $Ï$ momenta. We find sizeable reductions in the nuclear cross sections with respect to the elementary one, using a $Ï$ selfenergy which implies a width about six times the free one at normal nuclear density. The calculations are done to match the set up for an ongoing experiment at {\it SPring8/Osaka} which should provide valuable information on the renormalization of the $Ï$ properties in nuclei.
