Abstract
Observed transitions in the reaction /sup 12/C(..pi../sup +/, p) /sup 11/C at 49.3 MeV confirm the importance of multistep processes in the reaction mechanism. The relative intensitu of the transitions is nearly the same as in the reaction /sup 12/C(p, d) /sup 11/C at 700 MeV, except for an apparent isospin selection rule. Transitions to low-lying states in /sup 10/C via the reaction /sup 12/C(..pi../sup +/, d) have also been observed.
