Scientific organization of the talks:  Dr. Stephan Dürr and Prof. Thomas Udem

Precision measurements of the Rydberg spectra of H, He and H2 will be presented, which aim at determining their ionization energies and, in the case of H2, also the spin-rovibrational energy-level structure of H2+. These measurements are carried out for comparison with the results of first-principles calculations that include the treatment of finite-nuclear-size effects and relativistic and quantum-electrodynamics corrections up to high order in the fine-structure constant.
