The cross section for true absorption of positive pions in carbon was obtained from experiments at 85, 125, 165, 205, and 245 MeV. The results are compared with theoretical calculations. The total +-carbon cross section is decomposed into its major channels: elastic scattering, inclusive inelastic scattering, true absorption, and single charge exchange, as a function of pion energy. The inclusive + angular distribution was also measured and the results suggest that quasifree processes play an important role for backword scattering.
