The four-body breakup of spatially aligned D2 by 58.8 eV photons has been investigated by measuring the three dimensional momentum vector of both fragment ions and one of the two electrons in coincidence. Energy and angular correlation between ion and electrons is discussed. We find significant differences in the angular distribution between He and D2 as well as between the molecular orientation parallel and perpendicular to the polarization.
