Abstract: Method of differential cross sections calculation has been proposed for inelastic diffractive scattering of clustered nuclei by even-even nuclei with excitation of low-lying collective states. The method satisfactorily describes the experimental angular distributions of inelastic scattering cross sections of 6Li nuclei by 12C and 28Si nuclei with the excitation of 2+ states (4.44 and 1.78 MeV, respectively).
Keywords: nuclear diffraction, clustered nuclei, inelastic scattering, low-lying collective states.
