摘　　要：The a＋^2＋ Ne elastic scattering angular distributions at lower incident energies of Eα= 12.7-31.1 Me V have been analyzed by using the a-folding potential based on the α＋^16O structure model of the ^20Ne nucleus. The a-folding potential with a standard Woods-Saxon type imaginary part, can reasonably describe experimental cross sections and the anomalous large angle scattering （ALAS） features. The anomaly of the a＋^20Ne scattering system is further confirmed , in the lower incident energy region.
