Description

The results of the D(γ,pπ-) and 4He(γ,pπ-) reactions in the Δ(1236) region are given. For high values of the momentum of the undetected recoil. Significant deviations from the impulse approximation model are found. A tentative explanation of these discrepancies in term of π-N rescattering or π-reabsorption is given

Abstract (French)

On presente les resultats de l'etude des reactions D(γ,pπ-) et 4He(γ,pπ-) dans le region du Δ(1236). Pour des valeurs elevees de l'impulsion du recul non detecte, on trouve des deviations importantes par rapport a un modele de nucleon quasi libre. Differents processus de rediffusion π-N ou de reabsorption de π sont envisages pour expliquer le comportement des sections efficaces
