A method of deriving the Glauber amplitude (directly from its Glauber formula) for elastic scattering of hydrogenlike ions by structureless charged particles is presented. It is shown that the scattering amplitude in this case is composed of two parts; one (T/sup A//sub G/) is interpreted as the Coulomb-corrected Glauber amplitude of elastic scattering by the core neutral atom of the ion, and the other (T/sup C//sub G/) as the elastic-scattering amplitude of the residual nuclear Coulomb field. Both these terms are proven to be expressible in closed form. The residual Coulomb scattering term is found to be exactly identical to the one obtained directly by Schiff. The present method of derivation also guarantees a correct relative phase for these two terms T/sup C//sub G/ and T/sup A//sub G/. The formula obtained is applied to compute the differential cross sections of e/sup -/-He/sup +/ elastic scattering in the ground state.
