MEASUREMENT OF POLARIZATION OBSERVABLES IN THE (D)OVER-RIGHT-ARROW-](P)OVER-RIGHT-ARROW+P+N REACTION AT T-D=2.0 GEV(P)

We have studied the deuteron breakup in the p(d,2p)n reaction at T-d=2 .0 GeV. In this experiment, the vector analyzing power A(Y), the tenso r analyzing power A(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. Mar ked deviations from the impulse approximation using conventional deute ron wave functions are observed. Corrections due to the multiple scatt ering, the final state interaction, and the Delta excitation are calcu lated in a model where-the spin-isospin structure of the elementary am plitudes is treated rigorously. With this model, a reasonable account of the measured polarization observables is obtained. The global agree ment with all observables is, however, not good enough that we can rel iably discriminate between conventional wave functions.
