“…15. While the model of 8 B employed in these calculations is simplified to the extent that excitations of the 7 Be core are ignored, the 170.3 MeV 8 B + Nat Pb elastic scattering data of Yang et al [42] suggest that it is sufficiently realistic. Coupling effects are expected to be minimal at this energy -approximately three times the Coulomb barrier-and indeed the measured angular distribution shows a classic Fresnel scattering pattern [42].…”

However, calculations for near-barrier energies suggest that any suppression of the nuclear-Coulomb interference peak for 8 B + 208 Pb elastic scattering will be due largely to "static" effects rather than coupling to the continuum [26].…”

Abstract. Accurate elastic scattering angular distribution data measured at bombarding energies just above the Coulomb barrier have shapes that can markedly differ from or be the same as the expected classical Fresnel scattering pattern depending on the structure of the projectile, the target or both. Examples are given such as 18 O + 184 W and 16 O + 148,152 Sm, where the expected rise above Rutherford scattering due to Coulomb-nuclear interference is damped by coupling to the target excited states, and the extreme case of 11 Li scattering, where coupling to the 9 Li + n + n continuum leads to an elastic scattering shape that cannot be reproduced by any standard optical model parameter set. An early indication that the projectile structure can modify the elastic scattering angular distribution was the large vector analyzing powers observed in polarised 6 Li scattering. The recent availability of high-quality 6 He, 11 Li and 11 Be data provides further examples of the influence that coupling effects can have on elastic scattering. Conditions for strong projectile-target coupling effects are presented with special emphasis on the importance of the beam-target charge combination being large enough to bring about the strong coupling effects. Several measurements are proposed that can lead to further understanding of strong coupling effects by both inelastic excitation and nucleon transfer on near-barrier elastic scattering. A final note on the anomalous nature of 8 B elastic scattering is presented as it possesses a more or less normal Fresnel scattering shape whereas one would a priori not expect this due to the very low breakup threshold of 8 B. The special nature of 11 Li is presented as it is predicted that no matter how far above the Coulomb barrier the elastic scattering is measured, its shape will not appear as Fresnel like whereas the elastic scattering of all other loosely bound nuclei studied to date should eventually do so as the incident energy is increased, making both 8 B and 11 Li truly "exotic".

“…We present here preliminary results on 8 B+ 58 Ni and 8 B+ 208 Pb elastic scattering. Data for the former reaction have been obtained around the Coulomb barrier [34], while the latter cross section has been measured far above the Coulomb barrier [35]. The 8 B projectile is typical of proton-halo nuclei, since its binding energy is very low (137 keV).…”

We extend the continuum discretized coupled channel method (CDCC) to a microscopic version, where the projectile is described by a microscopic cluster model. This generalization (MCDCC) only relies on nucleon-target interactions, and therefore presents an important predictive power. We briefly present an outline of the model, and provide recent examples with 7 Li and 8 B elastic scattering on different light and heavy targets. We show that the model can be applied to high energies, as well as to low energies.
