Abstract
The proton yields from the interaction of pions on nuclear targets with 12<~A<~181 were measured in the region of the Δ(3,3) resonance. The shift in proton energies with angle is analyzed in terms of the average number of nucleons that have participated in absorbing the pion's momentum and total energy. The effective number of interacting nucleons, for both π+ and π- incident, is found to be ∼ 3 for C12 and increasing to ∼ 5.5 for Ta181. These effective numbers of nucleons are also consistent with the ratio of proton yields from π+- and π - induced reactions.
