Journal ArticleDOI
The g-factor of the electron bound in hydrogen-like ions
M. Diederich,Hartmut Häffner,N. Hermanspahn,M. Immel,H.-J. Kluge,R. Ley,R. Mann,Wolfgang Quint,S. Stahl,J. Verdú,Günter Werth +10 more
TL;DR: In this article, the first results for the magnetic moment (g-factor) of hydrogen-like carbon (12C5+) were presented, and the experimental accuracy was high enough to verify the relativistic contribution to the g-factor on the 10-3 level.
Book ChapterDOI
A Possible New Value for the Electron Mass from g-Factor Measurements on Hydrogen-Like Ions
TL;DR: The mass of the electron in atomic units (m e) represents the largest error contribution in an experiment to determine the g-factor of an electron bounding in hydrogen-like carbon as discussed by the authors.

Transport of atoms in a quantum conveyor belt (10 pages)
Journal ArticleDOI
Testing atomic structure theories with high accuracy mass measurements on highly charged ions
Hartmut Häffner,N. Hermanspahn,Paul Indelicato,H.-J. Kluge,Eva Lindroth,V. Natarajan,Wolfgang Quint,S. Stahl,J. Verdú,Günter Werth +9 more
TL;DR: In this paper, the authors discussed the possibility of determining atomic binding energies of highly charged ions to better than 20 eV via cyclotron frequency measurements in a Penning trap, at this level of accuracy different contributions to the binding energies, like relativistic corrections, Breit corrections and QED corrections, can be measured.

TL;DR: In this article, a highly entangled pair of ions is created, a complete Bell-state projective measurement involving the source ion and one of the entangled pair is carried out, and state reconstruction conditioned on this measurement is performed on the other half of entangled pair.
