Abstract

Reactions A(γ, pi^+p) are considered to proceed through the formation of pion-proton pairs on delta constituents in nuclei. We develop the nonrelativistic operator for Δ^{++}(γ, pi^+)p process in an arbitrary frame. The calculated cross section for C12(γ, π^+p) reaction is compared to the existing experimental data.
