Abstract

The analysing power A_N is examined in the range of the Coulomb-hadron interference 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 small contributions of the hadron spin-flip amplitude.
