We propose an exposure of O. 6 events/μb for antiprotons as close as possible to 150 GeV/c in the FNAL 30-inch Bubble Chamber-Proportional Wire Chamber: Hybrid Spectrometer System. We request these exposures as soon as suitably enriched beams of antiprotons are available to the spectrometer system. For a beam with antiprotons consisting of a fraction f of the total beam and eight beam tracks per picture, an exposure of 62,500/f pictures will yield 25,000 events for the study. An integral part of the proposal is an effort to seek improved methods of obtaining antiproton-enriched beams, and to complete the forward gamma detector now under construction. The purpose of this study is to gain some insight into the consequences of the difference between the valence quark makeup of protons and antiprotons. This will be accomplished by comparing the interactions proposed here with the p-p interactions being studied at the same energy in E-299. In particular. the availability of the forward gamma detector will enable us to compare the p⁺,p^⁻, and p⁰ production in the central region in the two processes.
