The electron magnetic moment,-μ/μ B= g/2= 1.001 159 652 180 59 (13)[0.13 ppt], is
determined 2.2 times more accurately than the value that stood for fourteen years. The most …

Abstract The Baryon Antibaryon Symmetry Experiment (BASE) aims at performing a
stringent test of the combined charge parity and time reversal (CPT) symmetry by comparing …

A measurement using a one-electron quantum cyclotron gives the electron magnetic
moment in Bohr magnetons, g/2= 1.001 159 652 180 73 (28)[0.28 ppt], with an uncertainty …

Measurements with a one-electron quantum cyclotron determine the electron magnetic
moment, given by g/2= 1.001 159 652 180 73 (28)[0.28 ppt], and the fine structure constant …

A new measurement resolves cyclotron and spin levels for a single-electron quantum
cyclotron to obtain an electron magnetic moment, given by g/2= 1.001 159 652 180 85 …

Quantum electrodynamics (QED) predicts a relationship between the dimensionless
magnetic moment of the electron (g) and the fine structure constant (α). A new measurement …

We propose using trapped electrons as high-Q resonators for detecting meV dark photon
dark matter. When the rest energy of the dark photon matches the energy splitting of the two …

The research reactor TRIGA Mainz is an ideal facility to provide neutron-rich nuclides with
production rates sufficiently large for mass spectrometric and laser spectroscopic studies …

A novel technique for a direct and coherent measurement of the modified cyclotron
frequency of an ion in a Penning trap at energies close to the thermal cooling limit is …

Cooling of particles to mK-temperatures is essential for a variety of experiments with trapped
