Abstract :
The differential cross section for the 12C(γ,π+p) reaction has been measured in the Δ(1232) resonance region at high recoil momenta of the residual nuclear system. The data are analyzed under the assumption that the formation of the π+p pairs may be interpreted as a γΔ++→π+p process which takes place on a Δ++ preexisting in the target nucleus. Estimates of the Δ++ momentum distribution View the MathML source fm3 for a mean momentum View the MathML source MeV/c as well as the number of Δ isobars per nucleon NΔ=0.017 were obtained for 12C.
