Abstract
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 17 O+ 208 Pb 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 17 O+ 208 Pb elastic scattering can be considered to be complementary to a previous measurement of the total reaction cross section for the system 17 F+ 208 Pb at energies of 86, 90.4 MeV [5, 6]. The data will be compared with those obtained for the neighboring systems 16,18 O+ 208 Pb and others available in literature.
Highlights
In the last decades the study of the reaction mechanisms at energies around the Coulomb barrier for halo and weakly bound nuclei has attracted a large interest
We measured at the Laboratori Nazionali di Legnaro the elastic scattering process for the system 17O+208Pb in the energy range 80 - 87 MeV
The detector signals are read by using standard electronic chains both for the silicon ΔE layers and the ionization chambers, while 32-channel ASIC chips manufactured by IDEAS-GM are employed for the E stages
Summary
In the last decades the study of the reaction mechanisms at energies around the Coulomb barrier for halo and weakly bound nuclei has attracted a large interest. The peculiar characteristics of these nuclei can affect deeply their reaction dynamics increasing or enhancing the total reaction cross section and/or specific reaction channels (for instance, breakup, transfer, fusion). It is quite important to have a large and reliable systematics of reaction cross section measurements for stable nuclei interacting with light, medium and heavy targets in order to compare the behavior of exotic nuclei with that of stable and strongly bound nuclei.
