The Lead Radius Experiment at Jefferson Laboratory

C. J. Horowitz, Indiana University, Bloomington
Building 6008 Conference Room

The Lead Radius Experiment (PREX) uses parity violating electron scattering to measure the neutron radius of 208Pb. This electroweak reaction is free from most strong interaction uncertainties. We describe the experiment, present first results, and discuss some of the implications for nuclear structure, atomic parity violation, and neutron rich matter in astrophysics.
