The reaction 141 Pr(α,n) 144 Pm was investigated between Eα = 11 MeV and 15 MeV with the activation method using the γγ coincidence method with a segmented clover-type high-purity Germanium (HPGe) detector. Measurements with four other HPGe detectors were additionally made. The comparison proves that the γγ coincidence method is an excellent tool to investigate cross sections down to the microbarn range. The (α,n) reaction at low energy is especially suited to test α + nucleus optical-model… 
Investigation of reactions relevant for the γ process using in-beam γ-ray spectroscopy
The reaction 89Y(p, γ)90Zr was studied at five proton energies close to the Gamow window. This reaction is of astrophysical importance, since it is located in a mass region, where the p-nuclei
Measurement of (α,n) reaction crosssections of erbium isotopes for testingastrophysical rate predictions
The γ-process in core-collapse and/or type Ia supernova explosions is thought to explain the origin of the majority of the so-called p nuclei (the 35 protonrich isotopes between Se and Hg).
Calculation of Cross-sections and Astrophysical S-Factors for 62Ni(α,n) and 62Ni(α,γ) Reactions of Structural Fusion Material Nickel
AbstractNickel is an important element in fusion reactor technologies and astrophysical applications. Therefore, the knowledge of astrophysical S-factors and cross-sections on nickel isotopes is
Cross section of α -induced reactions on Au197 at sub-Coulomb energies
Statistical model calculations have to be used for the determination of reaction rates in large-scale reaction networks for heavy-element nucleosynthesis. A basic ingredient of such a calculation is
Nuclear physics uncertainties of the astrophysical gamma-process studied through the 64Zn(p,alpha)61Cu and 64Zn(p,gamma)65Ga reactions
In a recent work, the cross section measurement of the 64Zn(p,alpha)61Cu reaction was used to prove that the standard alpha-nucleus optical potentials used in astrophysical network calculation fail

Diploma thesis
It is shown why NP-hardness still holds when this subproblem Steiner trees is omitted by considering (highly) connected networks only and focussing on the satisfaction of the flow constraints, and how much effort in computation and implementation is really necessary to solve realistic scenarios in practice.
A prototype probability package named APPL (A Probability Programming Language) is presented that can be used to manipulate random variables and examples illustrate its use.
