We have measured the analyzing powers A/sub y/, A/sub x/x, A/sub y/y, and A/sub x/z for the kinematically incomplete three-nucleon breakup reaction /sup 1/H(d,p)pn at a deuteron bombarding energy of 16.0 MeV. Similar data for the elastic channel were obtained at the same time. Data were acquired at laboratory angles from 15.0/sup 0/ to 42.5/sup 0/. The detected proton continua extended over a range in excitation energy E* for the residual pn system, and this range varied from E*=0--2.6 MeV at 15.0/sup 0/ to E*=0--0.2 MeV at 42.5/sup 0/. The experimental energy resolution was about 150 keV (lab). The breakup tensor analyzing powers attain magnitudes as large as about 0.2 at the lowest excitation energies. Faddeev calculations have been performed for a variety of final-state configurations having E*=0 and 200 keV and indicate that a full kinematically incomplete calculation would probably show no major disagreement with the data.
