Resonant and nonresonant breakup of 11Be on a proton target

Full Faddeev-type calculations are performed for the breakup of Be-11 on a proton target at 63.7 MeV/nucleon incident energy. A simplified two-body model for Be-11 involves an inert Be-10(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. .
