Two step processes in pion single charge exchange on {sup 2}H at T{sub {pi}{sup +}}=239thinspMeV

Results from a measurement of the reaction {sup 2}H({pi}{sup +},pp){pi}{degree} at T{sub {pi}{sup +}}=239thinspMeV are presented. Because two protons were detected, the measurement was sensitive to events which involved both nucleons in a substantial way. Differential distributions are compared to the predictions of simple models. An integrated cross section for SCX (single charge exchange), with the emission of two protons each with kinetic energy {gt}25thinspMeV, is presented. {copyright} {ital 1998} {ital The American Physical Society}
