We have investigated the dp → ppn non-spectator breakup reaction obtained from the KEK l m liquid hydrogen bubble chamber exposed to a beam of deuterons at ten momenta in the range 2.0-3.7 GeV/c. The pn and pp effective mass distributions in the two momentum regions 2.0-2.9 GeV/c and 3.0-3.7 GeV/c show no structure.
