Measurements of 20 vector and tensor spin observables in {ital d}-{ital p} elastic scattering at a deuteron bombarding energy of 1.6 GeV (800 MeV equivalent proton beam energy) are reported. Of these 10 are two-spin observables and the remaining ten are three-spin observables. The two-spin observables, six of which have been measured for the first time, were measured in the four-momentum-transfer range 0.12 to 0.85 (GeV/{ital c}){sup 2}. The three-spin observables, of which eight were measured for the first time, were measured in the momentum-transfer range 0.2 to 0.85 (GeV/{ital c}){sup 2}. The magnitude of the average vector polarization of the deuteron beam was 0.3, and of the average tensor alignment was 0.85. A frozen spin-polarized proton target was utilized for these measurements. These results are compared with previous measurements when possible, and show a general agreement. They are also compared with the predictions of the relativistic-impulse approximation, and its modified version, which takes into account a nontrivial off-mass-shell behavior of nucleon-nucleon scattering amplitudes.
