A search for possible structure in the energy spectrum of forward going protons from the 12C(π+, 3p)X reaction was undertaken. The measurement was done for π+ momenta of 355, 375, and 405 MeV/c. No narrow (less than 20 MeV) structure was found. A broad structure corresponding to a quasi-free scattering of the pion before capture, superimposed on a continuum background, was observed. The data indicate that additional free nucleons or light products are usually present in the final state.
