Measurement of the energy of recoil particles was used to obtain the following data at 800 MeV incident proton energy: the differential cross section for elastic proton-proton scattering at laboratory angles ranging between 1.34/sup 0/ and 6.45/sup 0/, the analyzing power for elastic proton-proton scattering at laboratory angles ranging between 2.8/sup 0/ and 6.45/sup 0/, and the differential cross sections and analyzing powers for elastic proton-deuteron scattering at laboratory angles ranging between 3.97/sup 0/ and 13.1/sup 0/. The data were analyzed to obtain information about the hadronic parts of the proton-proton and proton-neutron forward scattering amplitudes. The ratio of the real to the imaginary parts of the forward p-p spin-independent amplitude was found to be 0.005 +- 0.04. The ratio of the summed moduli squared of the forward p-p double-spin-flip scattering amplitude to the modulus squared of the forward p-p spin-independent amplitude was found to be 0.16 +- 0.03. The real and the imaginary parts of the p-p spin-orbit scattering amplitude divided by sin theta were found to be 0.79 +- 0.05 fm and 0.18 +- 0.11 fm, respectively. Finally, the real and the imaginary parts of the p-n spin-orbit scattering amplitude divided by sin theta were found to be 0.79 +- 0.09 fm and -1.6 +- 0.03 fm, respectively. These values were compared with the results of recent phase-shift analyses and forward dispersion-relation calculation. 45 figures, 20 tables.
