The [sup 1]H([ital d],2[ital p])[ital n] deuteron breakup reaction was measured at 2 GeV deuteron energy in a kinematically complete experiment. Fivefold differential cross sections are given in a wide range of kinematical variables and analyzed in terms of impulse approximation and [ital NN] rescattering. The deuteron momentum density was determined and deviations were found depending on the value of the four-momentum transfer [vert bar][ital t][vert bar] in the scattering process. At low [vert bar][ital t][vert bar] the momentum densities are in good agreement with the impulse approximation whereas large discrepancies were found above [ital q][approx]200 MeV/[ital c] when the four-momentum transfer was large. Various possible origins of the anomalous behavior at high [ital q] values are discussed.
