The exclusive breakup of the Borromean nucleus Be-9 incident on a proton target at 5.67 MeV/nucleon was studied with a triple coincidence requirement between the two breakup a fragments and the recoiling proton. The analysis was performed using an event-by-event code in a full kinematics approach, and Q-value spectra, relative spectra, and energy spectra of all reaction products were determined. Clear signatures of the three breakup modes: alpha + alpha + n, Be-8 + n, and He-5 + He-4 were observed in the recoiling proton spectra and the rates of these modes were quantified.
