Using a homogeneous sodium-iodide luminescent chamber, the effective mass spectra of the two pions produced in the reaction e (as Fe/sup 59 /sup -/ +i p and up to st r e (as Fe/sup 59 /sup -/ + e (as Fe/sup 59 /sup 0/ + p at incident pion energies of 871, 775, and 682 Mev. A comprehensive survey of similar experiments is included to provide perspective for the interpretation of the results. A peak in the effective mass spectra with incident pions of 871 Mev is found between 580 and 660 Mev with high momentum transfers to the proton dominating. The possible relationship of this phenomenon to the existence of a J meson is discussed. Additionally, the possibility of peaking structures near 540 Mev in both the 775 and 682 Mev data is considered, with considerable reservation because of possible large errors. Finally, a possible tendency for the accumulation of events in the 350 Mev region of the effective mass spectrum is seen in the data collected at 682 Mev. The possibility that large systematic errors negate this final result does exist. The importance of the fact that this experiment was run in the vicinity of the second and third pion-nucleon resonances is emphasized in interpreting the results and comparing it to similar experiments.
