Abstract: | The francium atom offers an excellent laboratory to study electron-nucleus interactions. As the heaviest alkali, its atomic
properties can be calculated with high precision, and laser trapping methods now allow precision optical spectroscopy of many
isotopes. Recent measurements of the 7P1/2 hyperfine structure, when coupled with previous measurements of the ground state hyperfine structure reveal a hyperfine anomaly.
The change in anomaly between an even-N isotope and an odd-N isotope is sensitive to the radial distribution of the neutron magnetization.
