Elastic scattering of O-17+Pb-208 at energies near the Coulomb barrier

Within the frame of the commissioning of a new experimental apparatus EXPADES we undertook the measurement of the elastic scattering angular distribution for the system O-17+Pb-208 at energy around the Coulomb barrier. The reaction dynamics induced by loosely bound Radioactive Ion Beams is currently being extensively studied [4]. In particular the study of the elastic scattering process allows to obtain direct information on the total reaction cross section of the exotic nuclei. In order to understand the effect of the low binding energy on the reaction mechanism it is important to compare radioactive weakly bound nuclei with stable strongly-bound nuclei. In this framework the study of the O-17+Pb-208 elastic scattering can be considered to be complementary to a previous measurement of the total reaction cross section for the system F-17+Pb-208 at energies of 86, 90.4 MeV [5, 6]. The data will be compared with those obtained for the neighboring systems O-16,O-18+Pb-208 and others available in literature.
