Measuring the Weak Charge Radius of Pb$^{208}$ with PREX-II

Parity-violating electron scattering is a strong tool that can be used to probe the elusive neutron density in atomic nuclei. Recently, the parity-violating electron scattering experiment PREX-II made measurements of the weak charge radius of Pb$^{208}$. This measurement is a strong improvement over the results of the PREX experiment, now measuring the weak charge radius with an uncertainty of 1.4%. In this talk, I will detail the results of the PREX-II experiment and their implications on various nuclear matter systems. These include neutron stars, pure neutron matter, and on the saturation density of symmetric nuclear matter.
