The energy spectra of deuterons recoiling from a deuterium gas target bombarded by transversely polarized 796-MeV protons have been measured to obtain the differential cross sections, dσdt, and analyzing powers, Ay(t), for p→-d elastic scattering over a range of laboratory angles from 4.53° to 13.02°, corresponding to a range of four-momentum transfer squared, |t|, from 0.013 to 0.108 GeV2/c2. Employing several sets of nucleon-nucleon, N-N, amplitudes obtained from N-N phase shift analyses, comparisons are made between the experimental data and the predictions of a multiple scattering theory. In this region of four-momentum transfer, Ay is shown to depend almost entirely on the spin-independent and spin-orbit N-N amplitudes.

The differential cross-section for pd elastic scattering has been measured at 9.7, 12.8 and 15.8 GeV/ c for t -values up to −2 GeV 2 . The Glauber multiple scattering model has been used to analyse the data, the main interest being the double scattering region.

The elastic scattering of 600-MeV protons from light nuclei has been studied at the National Aeronautics Space Administration Space Radiation Effects Laboratory (SREL) synchrocyclotron. Differential cross sections have been obtained for the scattering of protons from hydrogen, deuterium, helium-3, and helium-4. Polarization was measured for deuterium and He4 nuclei. The p−p cross-section data are in excellent agreement with the predictions from the Livermore phase shifts. Small-angle p−D, p−He3 elastic scattering data are compared with calculations based on the multiple-scattering theories of Watson and Glauber.
