Angular distributions of the differential cross section sigma(E*,theta/sub 1//sup l/) and of the vector and tensor analyzing powers A/sub y/(E*,theta/sub 1//sup l/), A/sub xz/(E*,theta/sub 1//sup l/), A/sub xx/(E*,theta/sub 1//sup l/), A/sub yy/(E*,theta/sub 1//sup l/) for the 3-nucleon breakup reaction /sup 1/H(vector d,p)pn were measured for a deuteron bombarding energy of 16.0 MeV. The data are reported as functions of the excitation energy E* in the pn system and of the laboratory angle theta/sub 1//sup l/. Laboratory angles between 15 and 42.5/sup 0/ were studied. The excitation energy range varies from 0 to 2.6 MeV at 15/sup 0/ to 0 to 0.2 MeV at 42.5/sup 0/. An excitation energy range (bin) of 0.2 MeV, which corresponds to laboratory energy bins from 0.3 to 0.4 MeV, was used to partition the proton continua. The experimental laboratory energy resolution is about 0.15 MeV. Large effects are seen in the tensor analyzing powers, particularly in A/sub xz/, at the lowest excitation energies. Except for A/sub yy/, there is no similarity of the observed analyzing powers to the corresponding elastic-scattering analyzing powers. Some data for A/sub xz/(E*,theta/sub 1//sup l/) at other energies are also presented. 11 figures, 6 tables.
