Photopion reactions on deltas preexisting in nuclei
A. Fix, I. Glavanakov, Yu. Krechetov
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.
