The inclusive pion inelastic scattering and true absorption cross sections at 50 MeV were measured for C+ on natural Li, C, Fe, Nb, and Bi and for C- on C, Fe, and Bi. The results show that C- cross sections are much larger than C+, the difference being significantly larger than expected from a simple Coulomb calculation. In particular, in C12 the absorption of negative pions is about twice that of positive pions. NUCLEAR REACTIONS Li, C, Fe, Nb, Bi (C+, C+C) and C, Fe, Bi (C-, C-C), EC=50 MeV; measured (CC), transmission; deduced absorption.
