The Lead Radius Experiment ("PREX"), experiment number E06002, uses the parity violating weak neutral interaction to probe the neutron distribution in a heavy nucleus, namely 208Pb, thus measuring the RMS neutron radius to 1% accuracy, which has an important impact on nuclear theory.   The experiment is being performed by the   Hall A Parity Collaboration which has recently completed   HAPPEX   and   PVDIS .
