Abstract

The ( $π^{+}$ ,2p) and ( $π^{\pm}$ , pn) reactions were studied by coincidence detection of the outgoing nucleons on C, Fe, and Bi at 165 and 245 MeV and on ${}^{16}O$ and ${}^{18}O$ at 165 MeV. The quasideuteron component is identified and found to account for only about 10% of the absorption cross section for carbon down to about 2% for bismuth. With corrections for the final-state interaction of outgoing nucleons it amounts to at most 40%. The data indicate that quasideuteron absorption following pion scattering is not likely. The absorption on T=1 nucleon pairs is about 4% of that on quasideuterons.
