Several experiments have measured nominally-charge-symmetric scattering of pions from tritium ([sup 3]H) and [sup 3]He. These experiments have covered incident pion energies from 142 MeV to 295 MeV and scattering angles up to 110[degrees] in the laboratory. The results have been used to study charge-symmetry breaking and nuclear scattering systematics. This work has extended these measurements to angles near 180[degrees] for pion energies of 142 MeV, 180 MeV, 220 MeV, and 256 MeV, which bracket the [Delta][sub 33] pion-nucleon resonance. This is the most extensive set of [pi]T and [pi][sup 3]He data in this kinematical region. It will allow tests of scattering theory of pion-nucleus interactions and charge-symmetry breaking in back-angle scattering, and, within the limits of these two theories, it may help improve the understanding of the structure of these nuclei.
