Abstract

We report on measurements of the cross section and provide first data on spin correlation parameters A(TT)('') and A(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(2)=0.2 GeV2/c(2) at the elastic scattering peak to Q(2)=0.11 GeV2/c(2) at the Delta(1232) resonance. The data provide a stringent test of pion electroproduction models.
