The polarization of the recoil proton for {pi}{sup +}p and {pi}{sup {minus}}p elastic scattering has been measured for various angles at 547 MeV/c and 625 MeV/c in a collaborative experiment involving participants from the George Washington University: the University of California, Los Angeles; and Abilene Christian University. The experiment was performed at the P{sup 3} East experimental area of the Los Alamos Meson Physics Facility. Beam intensities varied from 0.4 to 1.0 {times} 10{sup 7} {pi}{sup {minus}} s/sec and from 3.0 to 10.0 {times} 10{sup 7} {pi}{sup +} s/sec. The size of the beam spot at the target was 1 cm in the horizontal direction by 2.5 cm in the vertical direction. A liquid-hydrogen target was used in a flask 5.7 cm in diameter and 10 cm high. The scattered pion and recoil proton were detected in coincidence using the large acceptance spectrometer (LAS) to detect and analyze the momentum of the pions and the JANUS recoil polarimeter to detect and measure the polarization of the protons. Results from this experiment are compared to analyzing power data previously taken by this group and to partial-wave analysis predictions.
