Polarization transfer for inclusive proton-nucleus inelastic scattering at 800 MeV

Abstract

The polarization-transfer observables ${D}_{\mathrm{NN}}$, ${D}_{\mathrm{SS}}$, ${D}_{\mathrm{LL}}$, ${\mathrm{D}}_{\mathrm{LS}}$, and ${D}_{\mathrm{SL}}$ have been measured at 800 MeV for polarized proton inelastic scattering from $^{1}\mathrm{H}$, $^{2}\mathrm{H}$, and $^{12}\mathrm{C}$ with energy losses up to about 400 MeV. The scattering angles in the laboratory were 5\ifmmode^\circ\else\textdegree\fi{}, 11\ifmmode^\circ\else\textdegree\fi{}, and 20\ifmmode^\circ\else\textdegree\fi{}. No large differences between the observables for the three targets were seen. The data for $^{12}\mathrm{C}$ in the quasielastic region are reasonably well explained by nonrelativistic and relativistic models of one-step quasifree scattering. Specifically nuclear effects appear small in both the quasielastic and delta regions.
