The analyzing powers in proton-deuteron elastic and proton-neutron
quasi-elastic scattering have been measured at small angles using a polarized
proton beam at the COSY storage ring incident on an unpolarized deuterium
target. The data were taken at 796~MeV and five higher energies from 1600~MeV
to 2400~MeV. The analyzing power in $pd$ elastic scattering was studied by
detecting the low energy recoil deuteron in telescopes placed symmetrically
in the COSY plane to the left and right of the beam whereas for $pn$
quasi-elastic scattering a low energy proton was registered in one of the
telescopes in coincidence with a fast scattered proton measured in the ANKE
magnetic spectrometer. Though the experiment explores new domains, the
results are consistent with the limited published information.
