Abstract

The reaction p(e,eprimepi+)X0 was studied with two high resolution magnetic spectrometers to search for narrow baryon resonances. A missing mass resolution of 2.0 MeV was achieved. A search for structures in the mass region of 0.97 < MX0 < 1.06 GeV yielded no significant signal. The yield ratio of p(e,eprimepi+)X0/p(e,eprimepi+)n was determined to be (-0.35 +/- 0.35) times 10-3 at 1.004 GeV and (0.34 +/- 0.42) times 10-3 at 1.044 GeV.
