The alpha+Ne-20 elastic scattering angular distributions at lower incident energies of E-alpha = 12.7-31.1 MeV have been analyzed by using the alpha-folding potential based on the alpha+O-16 structure model of the Ne-20 nucleus. The alpha-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 alpha+Ne-20 scattering system is further confirmed in the lower incident energy region.
