ELASTIC SCATTERING OF 146-MEV POLARIZED PROTONS BY DEUTERONS

The polarization and differential cross section of 146Mev pretons elastically scattered by deuterons were measured in the center-of-mass angular range from 3.9 to 170 deg . A description of the liquid deuterium target and detection apparatus which permitted the measurement of the elastic events over these angles is given. At small angles the proton was energy analyzed; at large angles the recoil partner of the proton, the deuteron, was identified and energy analyzed. Although the energy resolution of plus or minus 1.7 Mev and the angular resolution of plus or minus 2.0 deg were sufficient to separate quasi- elaatic events from elastic events at most angles, they were insufficient to resolve unambiguously the 2.3Mev inelaatic events resulting from the formation of virtual deuterons.
