Popis: Ratios of double-differential cross sections for incident 500-MeV pions are presented for ( π + , π + p) and ( π + , π − p) reactions on 12,13 C, 90 Zr, and 208 Pb. A comparison with intra-nuclear cascade-model calculations suggest that the outgoing pion spectra show a feature consistent with quasi-free scattering from the Δ − component of the nuclear ground state wave function.
