21.10.2010: Physics in the scale pan

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.

18.10.2010: Wishing isomers a long life

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 external Link (ESR) at GSI, Darmstadt, Germany ... >

03.09.2010: Hot Water in Cold Comets

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 external Link

27.07.2010: First mass determination of 96,97Kr by Penning-trap mass spectrometry

Members of our division participated in the first mass measurements of 96,97Kr using the ISOLTRAP external Link Penning-trap spectrometer at ISOLDE external Link, CERN, Geneva. (See also our news of 17.07.2010.) Several online journals are reporting on the successful mass measurements, here a selection:

11.05.2010: Trapped in vacuum: Searching for the island of stability with Penning traps

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.
Chemie.DE has published a detailed article about this work ... >

11.02.2010: First direct mass measurements of transuranium nuclides

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 external Link in Darmstadt, Germany (see our news of 11.02.2010). Numerous online journals have published detailed articles about this first successful foray into the region of superheavy elements.
