The elastic scattering of alpha-particle is analyzed in terms of the optical model over the energy 104-172.2 MeV for C-12, 48.7-146 MeV for O-16, 50-119 MeV for Mg-24, and 104, 166, 120 and 240 MeV for Si-28. We generate the real part of the optical model potential using the single folding model. In the single folding procedure, the ground state density of the target is folded with an effective density dependent alpha-nucleon interaction. For the imaginary part, the usual Woods Saxon form is used. The parameters of the effective density dependent alpha-nucleon interaction are determined by fitting the experimental data of elastic scattering. The effective interaction's parameters are optimized using the chi(2) criterion. We reasonably reproduce the elastic scattering cross sections for all studied systems. The obtained results reflect the success of our obtained alpha-nucleon effective interaction. (C) 2016 Elsevier B.V. All rights reserved.
