High-precision mass measurement of doubly magic Pb
Kathrin Kromer, Chunhai Lyu, Menno Door +10
The absolute atomic mass of Pb has been determined with a fractional uncertainty of by measuring the cyclotron-frequency ratio of Pb…
Hadronic vacuum polarization correction to atomic energy levels
Sören Breidenbach, Eugen Dizer, Halil Cakir +1
The shift of atomic energy levels due to hadronic vacuum polarization is evaluated in a semiempirical way for hydrogenlike ions and for muonic hydrogen. A parametric hadronic polar…
Mass-difference measurements on heavy nuclides with at an eV/c2 accuracy level with PENTATRAP
A. Rischka, H. Cakir, M. Door +13
First ever measurements of the ratios of free cyclotron frequencies of heavy highly charged ions with Z>50 with relative uncertainties close to 1e-11 are presented. Such accurate m…
Tests of physics beyond the Standard Model with single-electron ions
Vincent Debierre, Christoph H. Keitel, Zoltan Harman
A highly effective approach to the search for hypothetical new interactions through isotope shift spectroscopy of hydrogen-like ions is presented. A weighted difference of the g fa…
New Measurement Resolves Key Astrophysical Fe XVII Oscillator Strength Problem
Steffen Kühn, Charles Cheung, Natalia S. Oreshkina +19
One of the most enduring and intensively studied problems of X-ray astronomy is the disagreement of state-of-the art theory and observations for the intensity ratio of two Fe XVII…
