Abstract

We have measured the angular and momentum distributions of the scattered pions from the reactions 6Li+, π+d)4He and 12C+, π+d)10B in a coincidence experiment. We compare our results with two models based on the impulse approximation: a “one-step model” in which it is assumed that a pair of nucleons with a close spatial correlation is ejected simultaneously, and a “two-step model” in which it is assumed that the incident pion interacts with a single nucleon which then picks up a second nucleon of appropriate charge to form a deuteron. In the case of 6Li both models give almost identical results and describe the shapes of the measured angular and momentum distributions well. In the case of 12C the two-step model agrees more nearly with the experimental results.
