Abstract

In order to study the dynamics of ¹¹Li and ⁹Li beams in a strong electric field at energies around the Coulomb barrier, we measured at the ISACII-TRIUMF Facility the angular distribution of elastic and inelastic scattering of ¹¹Li+²⁰⁸Pb at 24.2 and 29.7 MeV and ⁹Li+²⁰⁸Pb at 24, 29.5 and 33 MeV laboratory energies. We present here the first determination of the angular distribution of the cross section of ⁹Li+²⁰⁸Pb. The results are compared with theoretical calculations using the double-folding São Paulo Potential (SPP) for the real part and a for the imaginary part a Woods-Saxon potential. A good overall agreement is obtained.
