Based on a microscopic description of the elastic scattering of relativistic heavy ions within the Glauber multiple scattering framework, we have analyzed the Saclay data on the elastic scattering of alpha-particles by p, /sup 4/He, /sup 12/C, and /sup 40,42,44,48/Ca in the energy range between T/sup lab//sub ..cap alpha../=1.37 and 2.55 GeV. This article is primarily devoted to the study of the reaction mechanism in a parameter-free analysis, and, therefore, all available experimental information on elastic nucleon--nucleon scattering and nuclear one-body form factors has been introduced as an input. Even when two-body correlations and the spin dependence of the nucleon--nucleon amplitude are neglected, the theoretical differential cross sections fit very nicely the experimental data at low momentum transfers with the exception of /sup 4/He+/sup 12/C scattering. The failure of the simple theory in this case may be due to (anomalous) correlation effects in the target nucleus /sup 12/C.
