Abstract
Measuring the spin structure of the resonances is important for understanding the strong force. The spin asymmetries for pion electroproduction can be used to measure this spin structure. The eg1b run was conducted using CLAS (CEBAF Large Acceptance Spectrometer) at the Thomas Jefferson National Accelerator Facility (TJNAF) in 2000 by the CLAS collaboration. A 1.6 GeV - 5.6 GeV polarized electron beam and polarized nuclear targets (composed of NH3 or ND3) were used, allowing spin asymmetries to be measured. This analysis is of the double spin asymmetry A" in the exclusive production of positive pions from a polarized proton (ep - > e7r+n). The two single spin asymmetries have also been measured.
