Abstract

Differential cross sections of α-elastic scattering have been measured for the target nuclei11B,12C,13C,14N,15N, and16O at E=48.7 and 54.1 MeV and for the nuclei17O,18O, and20Ne at E=54.1 MeV. The experimental results were analysed in terms of the optical model using different complex potentials. Special emphasis is given to the application of the double-folding approach for the real part of the potential. The imaginary part is expressed in terms of Fourier-Bessel functions. Differential cross sections for the α-16O scattering over a wide energy range and for the elastic α-scattering for nuclei in the mass range A=11 up to A=24 at E=54.1 MeV are analysed by this method. A close correlation between the absorptive part of the potential and nuclear deformation is observed.
