Abstract

We present the elastic scattering of the He-6+Pb-208 and the He-6+Au-197 systems at the laboratory energy of E (lab)=27 MeV within the framework of the McIntyre parametrization, and systematically investigate chi (2)/N analysis of both systems to obtain an excellent agreement between the theoretical results and the experimental data. We find large diffusivity parameters indicating long range absorption mechanisms. We also show that both systems lack both the nuclear and the Coulomb rainbow scattering for obtained S-matrix parameters.
