Abstract
The cross section and first data on the spin correlation parameters ATT′ and ATL′ in the invariant mass range covering the δ resonance region in inclusive electron-proton scattering was presented. The data was used to provide a stringent test for model predictions of polarization observables in electroproduction of pions. The results showed that the four-momentum transfer squared range from Q2 = 0.2 GeV2/c2 at elastic scattering peak to Q2 = 0.11 GeV2 at the δ(1232) resonance.
