Atomic mass determination of uranium-238
Kathrin Kromer, Chunhai Lyu, Jacek Bieroń +10
The atomic mass of uranium-238 has been determined to be , improving the literature uncertainty by two orders of magnitude. It is obtained from a m…
Observation of a low-lying metastable electronic state in highly charged lead by Penning-trap mass spectrometry
Kathrin Kromer, Chunhai Lyu, Menno Door +10
Highly charged ions (HCIs) offer many opportunities for next-generation clock research due to the vast landscape of available electronic transitions in different charge states. The…
Self-energy correction to energy levels of highly charged ions in a path integral formalism
Sreya Banerjee, Zoltán Harman
Self-energy corrections to the energy levels of bound electrons are calculated in the framework of path integrals. We arrive at the full fermion propagator, using methods of functi…
Path integral formalism for the free Dirac propagator in spherical coordinates
Sreya Banerjee, Zoltán Harman
The relativistic Green's function of a free spin-1/2 fermion is derived using the Feynman path integral formalism in spherical coordinates. The Green's function is reduced to an ex…
