Abstract

Experimental results are presented for the $\mathrm{pp}$ elastic-scattering single spin observable ${A}_{\mathrm{oono}}{=A}_{\mathrm{ooon}}{=A}_{N}=P,$ or the analyzing power, at 19 beam kinetic energies between 1795 and 2235 MeV. The typical c.m. angular range is $60--100\ifmmode^\circ\else\textdegree\fi{}.$ The measurements were performed at Saturne II with a vertically polarized beam and target (transverse to the beam direction and scattering plane), a magnetic spectrometer and a recoil detector, both instrumented with multiwire proportional chambers, and beam polarimeters.
