Double Spin Asymmetries in Electron-Nucleon Scattering in Halls B and C at Jlab
Abstract
Three experiments at JLAB have measured the double polarization asymmetries A||(x, Q2) in the nucleon resonance region, using polarized electron beams incident on polarized proton and deuteron targets. The analysis for the first experiment, egla in Hall B, is nearly finished and preliminary values of the spin structure function g1(x, Q2) and the first moment Γ1 (x) have been extracted. The other two experiments, one in Hall B and one in Hall C are still analysing data. Some results are presented.
