Abstract
The elastic scattering process for the nuclear reactions induced by the Radioactive Ion Beams 7Be and 8B on a 208Pb target was measured for the first time in the energy range around the Coulomb barrier. Extensive theoretical calculations within the framework of the optical model were performed. An excellent agreement between experimental data and theoretical predictions was achieved for the reaction 7Be + 208Pb, while a comprehensive understanding of the reaction dynamics induced by the more exotic projectile 8B is still far to be reached. Predictions of the cross section for the breakup for both systems will also be given.
Highlights
The reaction dynamics induced by light weakly-bound nuclei in the energy range around the Coulomb barrier is a quite interesting research topic in present-day nuclear physics
The 7Be experiment was carried out at the Laboratori Nazionali di Legnaro (LNL, Italy), where the radioactive ion beam was produced with the facility EXOTIC [12]
All the steps of the data evaluation and of the fitting procedure are described in [14] and here we discuss the results and the comparison with similar mass systems. Both bombarding energies and cross sections need to the normalize in order to account for the different Coulomb barrier and the different geometrical size of the colliding nuclei
Summary
The reaction dynamics induced by light weakly-bound nuclei in the energy range around the Coulomb barrier is a quite interesting research topic in present-day nuclear physics. We are going to compare reactions induced by projectiles with similar masses (in the range A = 6-8) and all interacting with the same target nucleus (208Pb).
