Invited talk
Accurate knowledge of thermonuclear reaction rates is important in understanding energy generation, neutrino luminosity and nucleosynthesis in stellar interiors.
Natural and Cosmic-ray-induced background can seriously limit the determination of reaction cross-sections at relevant energies for astrophysics. In order to improve the signal-to-noise ratio special care in experimental setups...

Stellar evolution and nucleosynthesis
Invited talk
Electron screening enhances nuclear reaction cross sections at low beam energies. This happens in many astrophysical scenarios, e.g. stellar burning or supernova explosions. Unfortunately, the process is still poorly understood. All currently used calculations are based on the very simple assumption that the electrons distributed evenly on a shell decrease the repulsive potential inside the...

Explosive scenarios in astrophysics: observations, theory, and experiments

The $\gamma$ process is assumed to play an important role in the nucleosynthesis of the majority of the
p nuclei. Since the network of the $\gamma$ process includes so many different reactions and - mainly
unstable - nuclei, cross-section values are predominantly calculated in the scope of the Hauser-
Feshbach statistical model. The values heavily depend on the nuclear physics...

7Be(p,g)8B still represents one of the major uncertainties on the predicted high energy component
of solar neutrino flux and it has also a direct impact on the 7Li abundance after the Big Bang Nucleosynthesis. Previous experiments producing data with useful precision were performed
in direct kinematics, using an intense proton beam on a radioactive 7Be target. The
complicated target...
