By measuring the energy spectra of recoil particles, the following data have been obtained at an incident proton energy of 796 MeV: (1) the differential cross section for proton-proton (p-p) elastic scattering at laboratory angles between 1.37/sup 0/ and 6.40/sup 0/, and (2) the analyzing power for p-p elastic scattering at laboratory angles between 3.13/sup 0/ and 6.40/sup 0/. Analyses of these data have determined certain parameters characterizing the nuclear amplitude for p-p elastic scattering. The ratio, rho, 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 R of the summed moduli squared of the forward p-p double spin flip scattering amplitudes to the modulus squared of the forward p-p spin independent amplitude was found to be 0.16 +- 0.03. The real and imaginary parts of the p-p spin orbit scattering amplitude divided by sintheta were found to be 0.72 +- 0.05 and 0.18 +- 0.11 fm, respectively. These values are compared with results of recent phase-shift analyses and forward dispersion relation calculations.
