Measurements of F2 and R = sigmaL/sigmaT on Nuclear Targets in the Nucleon Resonance Region

Jefferson Lab Experiment E04-001 used the Rosenbluth technique to measure R = sigmaL/sigmaT and F 2 on nuclear targets. This experiment was part of a multilab effort to investigate quark-hadron duality and the electromagnetic and weak structure of the nuclei in the nucleon resonance region. In addition to the studies of quark-hadron duality in electron scattering on nuclear targets, these data will be used as input form factors in future analysis of neutrino data which investigate quark-hadron duality of the nucleon and nuclear axial structure functions. An important goal of this experiment is to provide precise data which to allow a reduction in uncertainties in neutrino oscillation parameters for neutrino oscillation experiments (K2K, MINOS). This inclusive experiment was completed in July 2007 at Jefferson Lab where the Hall C High Momentum Spectrometer detected the scattered electron. Measurements were done in the nuclear resonance region (1 < W2 < 4 GeV2) spanning the four-momentum transfer range 0.5 < Q2 < 4.5 (GeV 2). Data was collected from four nuclear targets: C, Al, Fe and Cu.
