The inclusive A([gamma ], [pi ] + [pi ] [ m i n u s ] )X reaction is studied theoretically. A sizable enhancement of the cross section is found, in comparison with the scaling of the deuteron cross section ([sigma ] d A/2). This enhancement is due to the modifications in the nuclear medium of the [gamma ]N [rarr ] [pi ][pi ]N amplitude and the pion dispersion relation. The enhancement is found to be bigger than the one already observed in the ([pi ], [pi ][pi ]) reaction in nuclei.
