In order to weigh atomic nuclei, Klaus Blaum, director at the Max Planck Institute for Nuclear Physics in Heidelberg, and his coworkers use ingenious tricks and thus help to solve far-reaching problems of physics. For example the nucleosynthesis of the chemical elements in stars or the nature of the dark matter, which is the "glue" that holds the universe together.

The American Physical Society has published a synopsis about the discovery of highly excited long-lived isomers through direct mass measurements at the Experimental Storage Ring (ESR) at GSI, Darmstadt, Germany ... >

Comets, also named "dirty snowballs", are largely composed of water. An international research team around Andreas Wolf, group leader in the research field "Molecular quantum dynamics and stored ion beams" of the division, recently succeeded deciphering an important aspect of the way by which water molecules often form in space. As a surprise, the water molecules produced under cold, dilute conditions turned out to be produced as particles as hot as 60,000 Kelvin. In their research the physicists, though, did not use a telescope, but a particle accelerator. Read more about the successful experiments in the press release of the idw
Members of our division participated in the first mass measurements of 96,97Kr using the ISOLTRAP Penning-trap spectrometer at ISOLDE , CERN, Geneva. (See also our news of 17.07.2010.) Several online journals are reporting on the successful mass measurements, here a selection:
Division member Jens Ketelaer et al. are designing a precision scale for mass measurements
of artificial isotopes at the Research Reactor TRIGA Mainz.
The double-Penning trap mass spectrometer TRIGA-TRAP
will allow more accurate predictions for the position of the island of stability.

Members of our division participated in the first direct mass measurements
of the nobelium isotopes 252–254No within an international collaboration
under the leadership of GSI Helmholtzzentrum für Schwerionenforschung
in Darmstadt, Germany (see our news of 11.02.2010).
