Research Activities
(with Ronald Gilman and Charles Glashausser)

Our research is centered on studies of spin physics and subnucleonic effects in light nuclei using electron beams at the Thomas Jefferson National Accelerator Facility (JLAB) 6 GeV accelerator, CEBAF, in Virginia. We are also involved in planning the MINERvA experiment at FNAL, a proposed high statistics neutrino experiment. Our next major experiments at JLab are DVCS, a measurement of generalized parton distributions, and DVCS, G_En, a measurement of the neutron electric form factor. The primary goal of our experiments is to determine the basic structure of the nucleon and how that is modified in the nuclear environment. We are particularly interested in using spin degrees of freedom as a sensitive tool for probing nucleon structure. In order to study spin structure we built a large polarimeter that is mounted in the focal plane of the hadron spectrometer at CEBAF Hall A.
