Abstract. Supplementing the optical model potential by repulsive core Vc allows to model Anomalous Large Angle Scattering in the α-particle scattering. Motivated by recent discussions, an analytical Soliton Form Factor is used for Vc that may be interpreted as a storage for kinetic energy in compressed nuclear matter. Computed angular distributions with the proposed potential of optical model with a repulsive core in the cases of Carbon 12C and Oxygen 118O nuclei agree nicely with the experiment thus furnishing support for such a parametrization and compressibility moduli values, where K =318 ± 27% (15%) and K = 334 ± 20% (6%) MeV for the two systems α + 12C (α +16O) respectively.
