Elastic scattering and breakup angular distributions of the weakly bound radioactive nucleus 8 B on a 208 Pb target at an incident energy of 238 MeV, which corresponds to four times the Coulomb barrier, have been measured at the HIRFL-RIBLL facility (Institute of Modern Physics, Lanzhou). The data have been analyzed using the optical model and the continuum discretized coupled channels (CDCC) formalism. The measured and calculated elastic scattering angular distributions do not show any significant Coulomb rainbow suppression. The angular distribution for the breakup reaction was measured for the first time at this energy. The angular distribution of the 7 Be fragments could be reproduced considering elastic plus nonelastic breakup contributions, with the former evaluated with the CDCC calculations and the latter with the model of Ichimura, Austern, and Vincent [Phys. Rev. C 32, 431 (1985)]. The comparison of the breakup cross section of 8 B with that of 11 Be suggests that the Coulomb and centrifugal barriers encountered by the valence proton may suppress the breakup cross section.

“…The most common proton halo is the 8 B nuclei which has low break up threshold. The 8 B nuclei has a weakly bound proton with a proton separation energy Sp =0.137 MeV and its half-life is t1/2=770 ms. Nuclear reactions and densities involving short-lived 8 B nuclei have been extensively investigated by both nuclear astrophysicists, experimental and theoretical nuclear physicist (Aguilera et al, 2011;Aguilera, Martinez-Quiroz, Belyaeva, Kolata, & Leyte-Gonzalez, 2008;Aguilera et al, 2009;Aguilera, Martinez-Quiroz, Rosales, et al, 2008;Barioni et al, 2011;Camacho, Aguilera, Gomes, & Lubian, 2011;Camacho, Aguilera, Lubian, & Gomes, 2013;Carlson et al, 2015;Chandel, Dhiman, & Shyam, 2003;Horii, Takashina, Furumoto, Sakuragi, & Toki, 2010;Lubian et al, 2009;Lubian & Nunes, 2007;Mackintosh & Pang, 2013;Mitchell et al, 2010;Morcelle et al, 2017;Moro, Crespo, Nunes, & Thompson, 2002;Varga, Suzuki, & Tanihata, 1995;Yang et al, 2013). In the theoretical analysis microscopic and phenomenological potential approximations have been used in explaining the measured experimental data.…”

In the present work, the elastic scattering of the 8B+27Al reaction at two different energies have been examined using the microscopic double folding potential approximation within the framework of the optical model. The real part of the optical model has been obtained by using Fermi, Gaussian and Variational Monte Carlo (VMC) density distributions in the microscopic double folding model and the imaginary part has been taken as Woods-Saxon volume type. The results of our microscopic analysis are quite compatible with the experimental crosssection data. The reaction cross sections, the volume integrals of used potentials and their χ2/N errors have also been computed. This study is important in showing the effect of microscopically derived potentials in explaining the 8B+27Al experimental data published recently.
