Abstract
A systematic study has been made of the reactions and in the angular range from to at 3, 4, 5, 6, and 7 . An orthogonal dispersion magnetic spectrometer detected protons from interactions in hydrogen with momentum transfer () in excess of 0.5 . Well-defined peaks in the missing-mass spectra occurred at average masses of 1240±6, 1508±2, and 1683±3 MeV with average full widths of 102±4, 92±3, and 110±4 MeV, respectively. Below 2400 MeV no other significant enhancements were found. The production cross sections near are in qualitative agreement with the predictions of the statistical model. For each isobar the differential cross section at fixed energy varies as , where ; varies systematically with energy and tends toward the same value ( Ge) for each isobar at the upper limit of our energy range.
