Abstract

Quasi-elastic scattering of 6He at Elab=27 MeV from 197Au has been measured in the angular range of 6°-72° in the laboratory system employing LEDA and LAMP detection systems. These data, along previously analysed data of 6He + 208Pb at the same energy, are analysed using optical model calculations. The role of Coulomb dipole polarizability has been investigated. Large imaginary diffuseness parameters are required to fit the data. This result is an evidence for long range absorption mechanisms in 6He induced reactions.
