  The analysing power $A_N$ is examined in the range of the Coulomb-hadron
interferenceon on the basis of the experimental data from p_L = 6 GeV/c up to
200 GeV/c taking account of a phenomenological analysis at p_L = 6 GeV/c and a
dynamic high-energy spin model. The results are compared with the new RHIC data
at p_L = 100 GeV/c. The new experimental data obtained at RHIC indicate the
small contributions of the hadrons spin-flip amplitude.
