We have studied the deuteron breakup in the p(d,2p)n reaction at T{sub d}=2.0 GeV. In this experiment, the vector analyzing power A{sub Y}, the tensor analyzing power A{sub YY}, and the polarization of the forward scattered proton are measured close to the quasifree pp scattering kinematics. These observables are presented as a function of the neutron momentum ranging from 0.04 to 0.45 GeV/c in the rest frame of the deuteron. Marked deviations from the impulse approximation using conventional deuteron wave functions are observed. Corrections due to the multiple scattering, the final state interaction, and the {Delta} excitation are calculated in a model where the spin-isospin structure of the elementary amplitudes is treated rigorously. With this model, a reasonable account of the measured polarization observables is obtained. The global agreement with all observables is, however, not good enough that we can reliably discriminate between conventional wave functions. {copyright} {ital 1997} {ital The American Physical Society}
