<p class="MsoNormal">The
Lead Radius Experiment (PREx) uses parity violating electron scattering to
accurately measure the neutron radius of 208Pb. This fundamental measurement
has broad implications for nuclear structure, atomic parity nonconservation,
low energy tests of the standard model, and for astrophysics. We describe the
experiment, that is to be run at Jefferson Laboratory in the Spring of 2010,
and provide an introduction to neutron stars. Then we discuss the experiments
many implications. The distribution of neutrons in a heavy nucleus depends on
the strong interactions between neutrons. These are the same interactions that
determine the properties of neutron rich matter, important in astrophysics. We
end by describing how PREx will help determine the size, extent of the solid
crust, cooling rate, and composition of neutron stars. <o:p></o:p></p>
