Description

Three types of microscopic nucleus-nucleus optical potentials are constructed using three patterns for their real and imaginary parts. Two of these patterns are the real $V^H$ and imaginary $W^H$ parts of the potential which reproduces the high-energy amplitude of scattering in the microscopic Glauber-Sitenko theory. Another template $V^{DF}$ is calculated within the standard double-folding model with the exchange term included. For either of the three tested potentials, the contribution of real and imaginary patterns is adjusted by introducing two fitted factors. An acceptable agreement with the experimental data on elastic differential cross-sections was obtained for scattering the $^{16, 17}$O heavy-ions at about hundred Mev/nucleon on different target-nuclei. The relativization effect is also studied and found that, to somewhat, it improves the agreement with experimental data.
