for their interest and motivating discussion. We also thank the members of the scanning and measuring group for their important contributions to this work. menta were 2.35, 2.62, and 2.90 BeV/c. 4 The pictures were scanned for two-and four-pronged events originating within a restricted fiducial volume. Additional criteria were imposed to ensure that the measured momenta were significant. The events were measured on film plane digitizers. The geometric reconstruction for the events was done on an IBM 7090 using the Nevis Laboratories NP-54 program. 5 Kinematic fitting was done using the UCRL GUTS subroutine. 6 published); C. Baltay, J. Sandweiss, J. Sanford, H. Brown, M.In an exposure of the Brookhaven National Laboratory 20-in. hydrogen bubble chamber to a separated 7T + beam at TT + momenta of 2.35 BeV/c (center-of-mass energy £* = 2.30 BeV), 2.62 BeV/c (£*=2.41 BeV), and 2.90 BeV/c (E* = 2.52 BeV), we have observed production of the co°, p°, and r}° mesons. The production of the co°, p°, and if* is often accompanied by simultaneous production of the N* ++ . The momentum transfer in w° and p° production is characteristic of peripheral collisions and suggests a single-particle exchange for the production mechanism. The decay distributions for the a>°, p°, and the p + demonstrate the importance of modifying the single-particle-exchange model to include absorptive effects. An upper limit on the two-7r decay of the co° is set at 2%. The width of the rj° is found to be less than 10 MeV. Elastic-scattering distributions are presented.
