Clues to inner atomic life from subtle light-emission shifts: Hyperfine structure of light absorption by short-lived cadmium atom isotopes reveals characteristics of the nucleus that matter for high precision detection methods

Two main factors influence the cadmium atom's hyperfine structure. First, electrons orbiting the nucleus create a magnetic field resulting in a force affecting the nucleus, and splitting its absorption and emission line into a number of finer lines....
