Polarization Analyzing PowerAy(θ)inppElastic Scattering at 643, 787, and 796 MeV

Abstract

Data have been obtained for the polarization analyzing power $A_y\left(\theta \right)$ in $\mathrm{pp}$ elastic scattering from near 30° to 90° (c.m.) at 643, 787, and 796 MeV. Relative uncertainties are typically ± 0.003 with an overall normalization uncertainty of $\left(\{+1\mathrm{}\}\{-0.5\mathrm{}\}\right)\%$. Data are not consistent with existing phase-shift analyses.
