<span style="font-size:14.0pt;font-family:"Times New Roman",serif">The heavy nucleus 208Pb, with 44 more neutrons than protons, has a neutron rich skin. The PREX collaboration has now measured the thickness of this skin using parity violating electron scattering.
This constrains properties of neutron rich matter similar to the matter found in neutron stars. I compare PREX’s results for 208Pb to LIGO gravitational wave observations of a neutron star merger and to NICER X-ray telescope observations of the curvature of
space near a neutron star. I end with a discussion of additional PV electron scattering measurements including CREX for 48Ca.<b><o:p> </o:p></b></span></p>
