A new critical survey is presented of all half-life, decay-energy, and branching-ratio
measurements related to 20 superallowed 0+→ 0+ β decays. Included are 222 individual …

An overview and status report of the new trapping facility for highly charged ions at the
Gesellschaft für Schwerionenforschung is presented. The construction of this facility started …

Penning-trap mass spectrometry in atomic and nuclear physics has become a well-
established and reliable tool for the determination of atomic masses. In combination with …

A new critical survey is presented of all half-life, decay-energy, and branching-ratio
measurements related to 20 superallowed 0+→ 0+ β decays. Compared with our last …

Atomic physics techniques for the determination of ground-state properties of radioactive
isotopes are very sensitive and provide accurate masses, binding energies, Q-values …

We report new shell-model calculations of the isospin-symmetry-breaking correction δ C to
superallowed 0+→ 0+ nuclear β decay. The most important improvement is the inclusion of …

The mass of an atom incorporates all its constituents and their interactions. The difference
between the mass of an atom and the sum of its building blocks (the binding energy) is a …

Abstract The National Superconducting Cyclotron Laboratory (NSCL) at Michigan State
University (MSU) is a scientific user facility that offers beams of rare isotopes at a wide range …

The novel five-Penning-trap mass spectrometer Pentatrap is developed at the Max-Planck-
Institut für Kernphysik (MPIK), Heidelberg. Ions of interest are long-lived highly charged …

Ramsey's method of separated oscillatory fields is applied to the excitation of the cyclotron
motion of short-lived ions in a Penning trap to improve the precision of their measured mass …
