The analyzing power A in 28-GeV/c proton-proton elastic scattering was measured with use of a polarized proton target and a high-intensity unpolarized proton beam at the Brookhaven National Laboratory alternating gradient synchrotron. The P/sub perpendicular//sup 2/ range of 2.85 to 5.95 (GeV/c)/sup 2/ was covered with good precision. A small dip of about -3.5% was found near P/sub perpendicular//sup 2/ = 3.5 (GeV/c)/sup 2/ where a 24-GeV/c CERN experiment had reported a deep dip of about -16% with large errors. In the previously unexplored large-P/sub perpendicular//sup 2/ region near 6 (GeV/c)/sup 2/ these new large error points suggest the A may be rising.
