Influence of the nuclear shape on the hyperfine splitting of heavy muonic ions — •Niklas Michel, Natalia S. Oreshkina, and Christoph H. Keitel — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg

When a muon is bound by a heavy atomic nucleus, it is located much closer to the nucleus than the corresponding electrons, thus the muonic wave function has a considerable overlap with the nuclear one and the transition energies in muonic atoms can provide information on the nuclear structure. Therefore, we aim at an accurate description of the energy levels of heavy muonic atoms in the framework of relativistic quantum mechanics with an extended nuclear charge distribution. In addition, we also take into account the screening correction due to the interaction of the muon with the electrons and the leading corrections for the bound muon from quantum electrodynamics.
