The breakup of /sup 2/H induced by 156 MeV protons has been studied in the (p,2p) and the (p,pn) reactions in the kinematically complete measurement with the unique kinematic condition: The three nucleons are collinear in the center of mass system of three nucleons in the final state. Also we performed experiments having neighboring kinematic conditions. The d/sup 3/sigma/d..cap omega../sub 1/d..cap omega../sub 2/dE/sub 1/ spectrum gives a peak in the region far from the final-state interaction and the true quasifree interaction regions. In this region of interest d/sup 3/sigma/d..cap omega../sub 1/d..cap omega../sub 2/dE/sub 1/ is calculated by a model derived from the fixed-scattering-center approximation proposed by L'Huillier and Ballot with Benoist-Gueutal. The model gives a smooth minimum, while the experimental peak is very sharp and sensitive to theta/sub 3/. The fixed-scattering-center approximation explains the present experimental d/sup 3/sigma/d..cap omega../sub 1/d..cap omega../sub 2/dE/sub 1/ spectrum in the entire region fairly well except at this peak. Because of this, we consider this peak difficult to explain by the fixed-scattering-center approximation to the Faddeev equation solution. This peak is similar to that observed by Lambert et al. at 23 MeV. (AIP)
