    "abstract": "We have examined modifications to the nuclear weak charge due to small\ndifferences between the spatial distributions of neutrons and protons in the Cs\nnucleus. We derive approximate formulae to estimate the value and uncertainty\nof this modification based only on nuclear rms neutron and proton radii.\nPresent uncertainties in neutron distributions in Cs are difficult to quantify,\nbut we conclude that they should not be neglected when using atomic parity\nnonconservation experiments as a means to test the Standard Model.",
