Resonant and nonresonant breakup ofBe11on a proton target

Abstract

Full Faddeev-type calculations are performed for the breakup of $^{11}\mathrm{Be}$ on a proton target at 63.7 MeV/nucleon incident energy. A simplified two-body model for $^{11}\mathrm{Be}$ involves an inert $^{10}\mathrm{Be}({0}^{+})$ core and a valence neutron. Inclusive cross sections as a function of the proton angle are calculated around the well known resonance at ${E}_{r}=1.275$ MeV including both resonant and nonresonant contributions. A reasonable agreement between the calculated angular distributions and the data is obtained but a large discrepancy relative to similar CDCC calculations is found at small proton angles.
