Abstract

Different approaches towards the Coulomb phase evaluation are tested altogether with the nuclear amplitude driven by the three-component Pomeron [V.A. Petrov, A.V. Prokudin, Eur. Phys. J. C 23 (2002) 135-143]. It is shown that the Coulombic amplitude and its interference with the nuclear amplitude are described well by three different approaches at all energies and the difference is negligible at RHIC and LHC energies. The model reproduces the existing data in the Coulomb interference domain quite accurately without any adjustment of the parameters. As a consequence, we predict the differential cross section in the region of the Coulomb nucleon interference for both RHIC and LHC energies.
