Inclusive double-differential cross sections for 500-MeV pions are presented for C(π±,π±) at θlab of 30 °, 40 °, 50 °, 70 °, and 90 °; and for C(π-,π-) at 110 °. We compare the 50 ° and 70 ° data with C(e,e’) data at nearly the same momentum transfer. These spectra from very different probes are more similar than expected from an intranuclear cascade calculation, which includes the strong rescattering of pions that have energies near 180 MeV. Agreement of the calculated spectra and the pion data is improved if the nucleus is assumed to be nearly transparent to these pions.
