"Mass measurements on highly charged lead and uranium ions\r\nwith the Penning-trap mass spectrometer Pentatrap"^^ . "With the Penning-trap mass spectrometer Pentatrap it is possible to carry out mass ratio determinations with a relative uncertainty of a few times 10^(−12). This is achieved by using a stack of five cylindrical Penning traps in a strong, homogeneous 7T magnetic field, stabilized\r\nagainst environmental influences, which allows phase-sensitive detection methods on single highly charged ions. The core of this thesis are three peer-reviewed publications that present measurements with the mass spectrometer Pentatrap. The first and second publication present the determination of the atomic mass of lead-208 and uranium-238 to an unparalleled precision in the heavy mass sector of 7 and 6*10^(−11), respectively. These results directly\r\ncontribute to the mass “backbone”, a number of nuclides whose mass is known to high precision, allowing one to improve relative mass measurements in the range of heavy and\r\nsuperheavy nuclides as well as to determine the g-factor of the bound electron in heavy, hydrogenlike ions. In the third article, a metastable state with an excitation energy of around 31 eV was measured in 208Pb41+ as a mass difference on top of the absolute mass of the lead ion of ≈194 GeV/c^2 and compared to two ab initio multiconfiguration Dirac-Hartree-Fock atomic-structure calculations."^^ .
