Available experimental angular distributions for 6Li + 28Si elastic scattering in the energy range 16-318 MeV are reanalyzed phenomenologically based on an optical model using Woods-Saxon (WS) potentials for both real and imaginary parts as well as semi microscopically based on cluster folding potential. The generated cluster folding potential is based on the appreciable cluster structure and breakup of 6Li into a deuteron orbiting a core of α-particle. Although several data sets in a wide range of energies are subjected to investigation, the theoretical calculations using the different concerned potentials reproduce fairly well the experimental data in the whole energy range. The extracted real and imaginary volume integrals and reaction cross-sections values are compared to the previously reported ones, and they are found to be in good agreement.
