We measured the elastic differential cross sections for pp and pp scattering within the four-momentum transfer range 0.001 {le}{vert bar}t{vert bar}{le} 0.06 (GeV/c){sup 2} at center-of-mass energy 24.3 GeV. From the interface between the Coulomb and nuclear amplitudes, we obtain {rho}, the ratio of the real part to the imaginary part of the nuclear elastic amplitude at t = 0, and the slope of the forward diffractive peak. The measurement was performed as part of Experiment UA6 using a hydrogen gas-jet target and the beams of the CERN SPS in collision mode. The kinetic energy, E, recoil angle {theta}, and time-of-flight of the low energy scattered target proton (the recoil proton) was given by an array of silicon barrier detectors at 90{degree} to the beams.
