Research Interests

  • Research which uses the spin property of elementary particles to study fundamental problems in nuclear physics.
  • Precise measurement of small correlations between scattering rates and spin direction arising from parity violation, exploring the parity-violating components of the Standard Model of particle physics, as well as possible extensions of that model.
  • Measurement of neutron radius of heavy nuclei, with implications for neutron star astrophysics and analysis of atomic parity violatio

Research Spotlight


Mr. Lou Buda, Prof. Paul Souder, and Mr. Charles Brown working on final assembly of the Møller and ep detectors for experiment E-158 at the Stanford Linear Accelerator.
