(Diplom-Physiker, Dr. rer. nat, Privatdozent, apl. Prof.)
Professional interests and activities:
Atomic physics experiments, often using (fast or slow) ion beams
A recent talk shows some examples and gives background information:
- Atomic structure (spectra, relativistic effects, QED contributions, hyperfine
structure) and dynamics (lifetimes, branching ratios, special decay modes)
- Spectroscopy (EUV, soft-x-ray) with links to astrophysics
and plasma diagnostics
- Intercombination and forbidden transitions in multiply charged ions
Talk at Mullard Space Science Laboratory
and at Cambridge University (12/2006)
Much of the above
has been done at the Bochum Dynamitron-Tandem Laboratorium (DTL, now part of
RUBION ) with its superb facilities.
However, for some special work I have traveled to do
- Beam-foil spectroscopy of highly charged, very heavy ions at
GSI Darmstadt and at
Argonne National Laboratory (USA) (and for work with ions of
lower charge states to various other places, such as Oxford UK,
Brookhaven NY, Stockholm SE, Tucson AZ, Toledo OH, Daresbury UK, Liège BE),
- Heavy-ion storage ring experiments
(Precision atomic lifetime measurements
using TSR Heidelberg (now closed down), at MPIK),
- Electron beam ion trap (EBIT) atomic lifetime
and spectroscopy experiments (first) at
Gaithersburg and (later and mostly, by far) at the
University of California Lawrence
Livermore National Laboratory .
The EBIT group in LLNL's High Temperature
and Astrophysics Division (now the Physics Division) has become a second science home
base for me. In 2011 and 2012, the Heidelberg and Livermore EBIT
groups joined forces for experiments at the LCLS X-ray light source at SLAC
(Menlo Park, CA, USA), photoexciting ions trapped in the traveling FLASH EBIT from MPIK Heidelberg.
Since the Bochum physics faculty has phased out work in atomic physics at the Bochum accelerators,
I have become a freelance physicist, continuing to pursue my physics research
especially with experiments at Heidelberg, Livermore, and Liège.
Up to 2014, my research has been fairly regularly supported by the Deutsche Forschungsgemeinschaft DFG.
Evaluation of archival experimental data continues into partial retirement,
as does my spectroscopy teaching.
My association and address are with AIRUB,
the Astronomy Institute at Ruhr-Universtät Bochum,
by courtesy of Prof. Dr. R.-J. Dettmar. The institute is concerned with galaxy evolution,
a horizon much wider than my experience.
