Elastic and inelastic scattering measurements for the 13C+208Pb system at close to the Coulomb barrier energies

Abstract

Angular distributions for elastic and inelastic scattering of the 13C+208Pb system have been measured at energies close to the Coulomb barrier, Elab = 59.8, 63.8 and 65.8 MeV. Optical Model (OM) and coupled channel (CC) analysis were performed using Woods-Saxon and double folding São Paulo potentials. Angular distributions for the Jπ = 3/2− excited state of 13C∗ (3.684 MeV) and Jπ = 3− of 208Pb∗ (2.615 MeV) were also obtained and analyzed with coupled channels calculations. A good description of the elastic angular distributions was achieved with the inclusion of the 1n-stripping contribution in the coupled reaction channel (CRC) calculations.
