Spin-Dependent Electron-Proton Scattering in the Delta-Excitation Region
We report on measurements of the cross section and provide first data on spin correlation parameters A{sub TT'} and A{sub TL'} in inclusive scattering of longitudinally polarized electrons from nuclear-polarized hydrogen. Polarized electrons were injected into an electron storage ring operated at a beam energy of 720 MeV. Polarized hydrogen was produced by an atomic beam source and injected into an open-ended cylindrical cell, located in the electron storage ring. The four-momentum transfer squared ranged from Q{sup 2} = 0.2 GeV{sup 2}/c{sup 2} at the elastic scattering peak to Q{sup 2} = 0.11 GeV{sup 2}/c{sup 2} at the Delta (1232) resonance. The data provide a stringent test of pion electroproduction models.
