Measures absolute differential cross-sections. Uses the Crystal Ball multiphoton spectrometer with large acceptance and high energy resolution. Various reaction channels are identified by reconstructing the invariant mass of the produced gamma rays. The experiment has two distinct parts. The goal of BNL-913 is a better determination of the masses, widths, and decay modes of the excited states of the nucleon. The spokespersons are M.E. Sadler, H. Spinka and W.B. Tippens. BNL-914 studies the Lambda* and Sigma* resonances via their neutral decays. The incident beam momentum is varied in steps of 25 - 50 MeV/c from 600 MeV/c in the C-line to the maximum momentum of 1.8 GeV/c in the D-line. The spokespersons are T. Kycia, S.P. Kruglov and B.M.K. Nefkens. Approved for 1000 hours. Scheduled to run in FY 1997.
