Description
Charge form factors are fundamental observables for nuclear physics. Experimentally, few techniques can be used to probe nuclear charge distributions, the dominant ones being electron scattering, hadronic reactions or laser spectroscopy. The comparison between electrons and positrons provides a unique way to investigate higher order corrections to the Born approximation from which dispersive corrections are yet to be mapped out and applied to measured nuclear radii. The availability of (un)polarized electron/positron beams would provide a path to address this shortcoming, in addition to the use of radioactive targets to expand the study to a larger range of nuclei. This presentation will also discuss complementary analysis of recent rare isotope experiments conducted by the MoNA Collaboration to extract this observable and discuss future plans.
