| Abstract | |
An elastic backscattering experiment has been performed at energies below the Coulomb barrier to investigate static and dynamic effects in the interaction of He-6 with Bi-209. The measured cross sections are presented in terms of the d sigma/d sigma(Ruth) ratio, as a function of the distance of closest approach on a Rutherford trajectory. The data are compared with a three-body CDCC calculation and good agreement is observed. In addition, the critical distance of interaction was extracted. A larger value was obtained for the exotic He-6 nucleus as compared with the weakly bound Li-6 and Be-9 nuclei and the tightly bound He-4, C-12, and O-16 nuclei. (AU) | |
