Description
Coulomb-Nuclear Interference (CNI) mechanism of single-spin asymmetry in small-angle elastic scattering of polarized protons offers a unique way to measure the spin-flip part of the Pomeron. We analyze recent data from RHIC on single-spin asymmetry in pp and pA elastic scattering in the CNI region, aiming at determination of $r_5$, the fractional spin-flip component of the hadronic elastic amplitude. Some inconsistency is observed and possible reasons are discussed.
