Within the project area "Nuclear Astrophysics" our research group
deals with the synthesis of elements in different burning
stages (including explosive end phases) of stars. We concentrate on the research of the
production of heavy proton rich nuclei. The models for
nucleosynthesis ask for reliable and robust parameters
from nuclear physics, especially alpha- und proton-optical
potentials, gamma strength functions and level densities.
The knowledge about these paramters in heavy nuclei is rather limited.
In our experiments we try to find universal models for these
parameters. For this purpose we do:
-
Proton- and alpha-capture reactions using activation and in-beam
methods at the
Tandem accelerator
of the University of Cologne (UoC), at
PTB Braunschweig, at
RUBION of the Ruhr-Universität
Bochum.
-
Preparation of experiments for Nuclear Astrophysics at the new
Accelerator Mass Spectrometer
of the University of Cologne.
-
Network calculation in statistical models.
The projects are supported by Deutsche
Forschungsgemeinschaft (ZI 510/7-1, INST 216/544-1) and the
University of Cologne.
