    "abstract": "Parity violating elastic electron-nucleus scattering provides an accurate and\nmodel independent measurement of neutron densities, because the $Z^0$ couples\nprimarily to neutrons. Coulomb distortion corrections to the parity violating\nasymmetry $A_l$ are calculated exactly using a relativistic optical model.\nDistortions significantly reduce $A_l$ in a heavy nucleus. However even with\ndistortions, an experiment to measure the neutron radius is feasible. This will\naid the interpretation of future atomic parity violation measurements and\nprovide fundamental nuclear structure information. Coulomb distortions and\nsmall differences between neutron and proton radii could be important for a\nstandard model test on $^4$He, $^{12}$C or $^{16}$O.",
