“…An optical-model analysis with the São Paulo double-folding potential [33] was also performed for these data, giving good results. Total reaction cross sections were derived from these analyses and compared with the values for other systems with weakly-bound and stable projectiles, applying the two most-used reduction methods [31,32,67,68]. The conclusion is that reactions with non-halo light nuclear projectiles lead to similar total reaction cross sections [65].…”

Abstract. The present status of fusion reactions involving light (A < 20) radioactive projectiles at energies around the Coulomb barrier (E < 10 MeV per nucleon) is reviewed, emphasizing measurements made within the last decade. Data on elastic scattering (providing total reaction cross section information) and breakup channels for the involved systems, demonstrating the relationship between these and the fusion channel, are also reviewed. Similarities and differences in the behavior of fusion and total reaction cross section data concerning halo nuclei, weakly-bound but less exotic projectiles, and strongly-bound systems are discussed. One difference in the behavior of fusion excitation functions near the Coulomb barrier seems to emerge between neutron-halo and proton-halo systems. The role of charge has been investigated by comparing the fusion excitation functions, properly scaled, for different neutron-and proton-rich systems. Possible physical explanations for the observed differences are also reviewed.

“…Shorto et al [30] proposed to use the parametrization of equation (4) to analyze reaction cross sections by replacing the fusion cross section (σ F ) by the total reaction cross section (σ R ). Thus, considering the real part of the potential, we assumed that the sum of the nuclear and the Coulomb potentials near the barrier is described by a parabola:…”

Angular distributions for the elastic scattering of 8 B, 7 Be and 6 Li on 12 C target have been measured at E lab = 25.8 MeV, 18.8 MeV and 12.3 MeV, respectively. The analyses of these angular distributions have been performed in terms of the optical model using Woods-Saxon and double-folding type potentials. The effect of breakup in the elastic scattering of 8 B + 12 C is investigated by performing coupled-channels calculations with the Continuum Discretized Coupled Channel (CDCC) method and cluster-model folding potentials. Total reaction cross sections were deduced from the elastic scattering analysis and compared with published data on elastic scattering of other weakly-and tightly-bound projectiles on 12 C, as a function of energy. With the exception of 4 He and 16 O, the data can be described using a universal function for the reduced cross sections.

Abstract. The reaction dynamics induced by the 17 F Radioactive Ion Beam on the protonshell closed 58 Ni target was studied at two colliding energies slightly above the Coulomb barrier. Charged reaction products were detected at forward angles and the quasi-elastic differential cross section was analyzed within the framework of the optical model in order to extract the reaction cross section and to investigate the relevance of direct reaction channels (inelastic scattering, breakup and transfer) at near-barrier energies. The comparison with the reaction induced by double-magic tightly-bound 16 O projectiles on the same target showed that the 17 F reaction cross section is moderately enhanced at the lower secondary beam energy. Direct reaction channels were also found to be more relevant than for the corresponding 16 O-induced reaction.
