"Neutron Stars at JLAB and The Lead Radius Experiment"

Dr. Chuck J. Horowitz
Indiana University


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.
