Electrons bound in highly charged heavy ions such as hydrogen-like bismuth <sup>209</sup>Bi<sup>82+</sup> experience electromagnetic fields that are a million times stronger than in light atoms. Measuring the wavelength of light emitted and absorbed by these ions is therefore a sensitive testing ground for quantum electrodynamical (QED) effects and especially the electron-nucleus interaction under such extreme conditions. However, insufficient knowledge of the nuclear structure has prevented a r ...[more]
