Dr. Jeffery Secrest and co-authors have published a paper titled: The G0 Experiment for Parity-Violating Electron Scattering Measurements at Forward and Backward Angles in the journal Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment can be found in the August 2011 issue on pages 59-86.   In the paper, the parity-violating elastic scattering of electrons from protons and quasi-elastic scattering from deuterons is measured in order to determine the neutral weak currents of the nucleon.
