We investigate the effects of potentials with quadrupole and hexadecapole deformations on the elastic scattering angular distributions of deformed projectiles. We calculate the elastic scattering cross-sections of 20Ne + 12C, 22Ne + 12C, 24Mg + 24Mg and 28Si + 27Al reactions by using Deformed Broglia-Winther (1991) (DBW91), Deformed Aage Winther (DAW95) and Deformed Woods-Saxon (DWS) potentials. Then, we perform the calculations for different orientation angles such as θ = 0 and θ = π/2 of deformed projectiles. Finally, we compare the theoretical results together with the experimental data.
