Measurement of radiative α-capture cross sections on 98Ru and 144Sm for γ-process nucleosynthesis
Since p isotopes cannot be produced in neutron-capture reaction networks, a production mechanism via photodisintegration reactions was proposed - the γ process. The specifc path of this reaction
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
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).
Successful Prediction of Total α-Induced Reaction Cross Sections at Astrophysically Relevant Sub-Coulomb Energies Using a Novel Approach.
A simple barrier transmission model is suggested and it is shown that this simple model in combination with a well-chosen α-nucleus potential is able to predict total α-induced reaction cross sections for a wide range of heavy target nuclei above A≳150 with uncertainties below a factor of 2.
Impact of the α optical model potential on the γ -process nucleosynthesis
A. Simon et al., J. Phys. G 44 064006 (2017) g-process nucleosynthesis is a complex network of photodisintegration reactions on preexisting seed nuclei. Predicted to occur in an explosive
Cross-section measurements of radiative proton-capture reactions in Cd112 at energies of astrophysical interest
Reactions involving the group of nuclei commonly known as p nuclei are part of the nucleosynthetic mechanisms at astrophysical sites. The $^{113}$In nucleus is such a case with several open questions

Investigation of alpha-induced reactions on 130Ba and 132Ba and their importance for the synthesis of heavy p nuclei
Captures of alpha particles on the proton-richest Barium isotope, 130Ba, have been studied in order to provide cross section data for the modeling of the astrophysical gamma process. The cross
Determination of 141Pr(alpha,n)144Pm cross sections at energies of relevance for the astrophysical p-process using the gamma-gamma coincidence method
