Book excerpt: A measurement of the pp elastic scattering spin parameters are essential in determining the I = 1 amplitudes as well as contributing to the determination of phase shifts. The measurements of single and double-spin correlation parameters at each angle and energy will have a large impact on these programs. Furthermore, a study of the two-spin elastic scattering parameters may reveal possible new structure in the pp system. Experiment 512 has its objective to measure C/sub SS/ in the angular region 20° less than or equal to theta/sub c.m./ less than or equal to 90° and at energies of 500, 650 and 800 MeV. The EPB beam, polarized in the S direction, was incident to a target also polarized in the S direction. The scattered particles were detected in a single arm spectrometer which rotated from about 0° to 45° in the lab. A simultaneous measurement of .delta.sigma/sub T/ was made using the transmission counters from Experiment 498 downstream of the spectrometer. Results are presented. (WHK).
