Abstract
The goal of Jefferson Lab experiment E01-004 (Fpi-2) was the measurement of the longitudinal and transverse cross sections via pion electroproduction from hydrogen and deuterium for the purpose of extracting the charged pion form factor using pole dominance. The data were taken at two values of Q2 (1.60 and 2.45 (GeV/c)2). In order to attain full coverage in phi, charged pions were detected in parallel kinematics (along the direction of momentum transfer, q, and at +/- 3 degrees off the direction of momentum transfer. For each Q2 data were taken for two values of the virtual photon polarization, epsilon, respectively. All data were taken at a fixed center of mass energy, W=2.22 GeV. The longitudinal and transverse pieces of the cross section were separated using the Rosenbluth separation method.
