Inclusive (. pi. /sup +-/,. pi. /sup 0/) reactions in nuclei. [50 to 200 MeV, differential, total cross section yield]

Nuclear pion single charge exchange was studied using a method of ..pi../sup 0/ detection based on the spectroscopy of the back-angle decay ..gamma..-ray. Charge exchange scattering from nuclei ranging from Be to Pb was studied for incident pion energies of 50, 100, 150, and 200 MeV. The angular distributions and ..pi../sup 0/ energy spectra beyond 60/sup 0/ are dominated by effects characteristic of quasi-free scattering. Total charge exchange cross sections are larger than values suggested by optical model calculations. 7 references.
