Tensor and vector spin observables in p-d elastic scattering at 600, 800, and 1000 MeV

Abstract

Measurements of the tensor and vector spin observables C(0,NN,0,0), C(0,SS,0,0), and C(0,N,0,0), in p-d elastic scattering at 600, 800, and 1000 MeV equivalent proton bombarding energy, are reported. The data were taken in the range 0.1<-t<1.2 (GeV/c${)}^{2}$. The experiment employed a polarized deuteron beam with tensor and vector components of \ifmmode\pm\else\textpm\fi{}0.75 and \ifmmode\pm\else\textpm\fi{}0.25, respectively, a liquid hydrogen target, and a single arm magnetic spectrometer. The tensor and vector spin parameters C(0,N,0,0) and C(0,NN,0,0) were extracted from the data with beam polarization normal to the scattering plane. The observable C(0,SS,0,0) was obtained by precessing the deuteron polarization into the scattering plane. Comparison of the data with the predictions of a relativistic multiple scattering theory is made.
