For Run Info, see the Wiki: prex.jlab.org
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 .
