  • Measuring the electron affinity, a fundamental chemical property, has been challenging for rare elements due to sensitivity limitations. Here, the authors present a novel ion-trap technique capable of performing high-precision affinity measurements with orders of magnitude fewer samples.

  • The masses of the exotic calcium isotopes 53Ca and 54Ca measured by a multi-reflection time-of-flight method confirm predictions of calculations including nuclear three-body interactions.

  • The difference between the mass of an atom and the sum of its building blocks (the binding energy) is a manifestation of Einstein's famous relation E = mc2. Superheavy elements have been observed, but our present knowledge of the binding energy of these nuclides is based only on the detection of their decay products, although they represent the gateway to the predicted 'island of stability'. Here, direct mass measurements of trans-uranium nuclides are reported, providing reliable anchor points en route to the island of stability.

  • Measurements of low-energy electronic states of radium monofluoride validate predictions of the use of this short-lived radioactive molecule in exploring fundamental physics and provide evidence of its suitability for laser cooling.

  • Spectroscopy and shell model calculations reveal the 181Hg isotope as the endpoint of the shape-staggering of Hg nuclei, a consequence of neutron removal which arises from the interplay of single-particle and collective degrees of freedom.
