Abstract

A new S-matrix model is proposed to describe refraction effects in the intermediate energy light nucleus elastic scattering on atomic nuclei. An analysis of experimental data on scattering of ⁴He, ⁶Li and ¹⁶O nuclei by different target nuclei is made on the basis of this model and the near-far decomposition of the scattering amplitude. Comparison of our results with those obtained by the optical model is discussed.
