Abstract
The four-body breakup reaction has been studied in a geometry chosen to emphasize the double spectator process. Data were obtained at a bombarding energy of 80 MeV for the coincident detection of both emitted protons at several equal angle pairs. Comparison with simple plane wave Born approximation calculations suggests that, in addition to the double spectator process, another process, more strongly localized in phase space, is important. It is suggested that such a process is the double spin-flip excitation of both deuterons to the singlet state.
