  • Measurement of the bound-state β− decay of 205Tl81+ gives a new, longer half-life, allowing for the calculation of accurate stellar 205Pb yields and the isolation time of the early Solar System.

  • A high-precision measurement of the shielding effects of multiple electrons on the nuclear magnetic moment is made possible by spectroscopy of hydrogen-like 9Be3+, which overcomes limitations from the nuclear structure.

  • In addition to hyperfine splitting effects, isotope shifts of atomic electronic energy levels allow the investigation nuclear properties. Here, the authors study the isotope dependence of the Zeeman effect in litihium-like calcium isotopes in a Penning-trap setup and find good agreement with QED calculations.

  • By trapping and crystallizing two highly charged ions of different neon isotopes in the same potential, a high-precision measurement of the bound-electron g-factor difference is obtained.

  • Measurements of the hyperfine structure of chemical elements isotopes provide unique insight into the atomic nucleus in a nuclear model-independent way. The authors present collinear laser spectroscopy data obtained at the CERN ISOLDE and measure hyperfine splitting along a long chain of odd-mass tin isotopes.
