Abstract

Complete angular distributions for the reactions Sn-112,Sn-124(alpha,alpha)(112,124) Sn have been measured at different energies around the Coulomb barrier. Preliminary results for the Sn-112 circle times alpha and Sn-124 circle times alpha potentials at the energy E-c.m. approximate to 19 MeV are presented. The full determination of the a-nucleus potential for both nuclides may also help to understand the behaviour of a-nucleus potentials along an isotopic chain.
