  Spin-dependent pomeron effects are analyzed for elastic $pp$ scattering and
calculations for spin-dependent differential cross sections, analyzing power
and double-spin correlation parameters are carried out for the energy range of
the Relativistic Heavy Ion Collider (RHIC) at BNL. In this energy range, $50
\leq \sqrt{s} \leq 500 \gev$, the structure of pomeron-proton coupling can be
measured at RHIC with colliding polarized proton beams.
