Cross-section measurements relevant for the astrophysical p process at the University of Cologne
The astrophysical p process unites all processes that have been introduced to explain the abundance of a group of 30 to 35 neutron-deficient nuclei which are referred to as p nuclei. In general, these
Investigating the Ag109(p,γ)Cd110 reaction and its underlying nuclear physics
Background: The nucleosynthesis of neutron-deficient $p$ nuclei remains an unsolved puzzle in nuclear astrophysics. Most likely, huge networks containing hundreds of nuclear reactions are responsible
Absolute Mo96(p,n)Tc96m+g cross sections and a new branching for the Tc96m decay
Background: Radionuclides in the Mo-Tc region play an important role in modern medical diagnostics. These applications require a $\ensuremath{\gamma}$-emitting radioisotope that is injected into the
Deducing primary γ -ray intensities and the dipole strength function in Mo94 via radiative proton capture
Background: The nucleosynthesis of heavy nuclei is affected by the reaction rates of radiative capture reactions. Many of the astrophysical relevant rates cannot be obtained from experiments but are


The activation method for cross section measurements in nuclear astrophysics
Abstract.The primary aim of experimental nuclear astrophysics is to determine the rates of nuclear reactions taking place in stars in various astrophysical conditions. These reaction rates are an
Direct study of the α -nucleus optical potential at astrophysical energies using the Zn 64 (p,α) Cu 61 reaction
In the model calculations of heavy element nucleosynthesis processes the nuclear reaction rates are taken from statistical model calculations which utilize various nuclear input parameters. It 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).
Test of statistical model cross section calculations for α -induced reactions on Ag 107 at energies of astrophysical interest
Background: Astrophysical reaction rates,which are mostly derived from theoretical cross sections, are necessary input to nuclear reaction network simulations for studying the origin of p nuclei.
Experimental study of the astrophysical γ -process reaction 124Xe(α ,γ )128Ba
Background: The synthesis of heavy, proton rich isotopes in the astrophysical γ process proceeds through photodisintegration reactions. For the improved understanding of the process, the rates of the
Proton capture reaction cross section measurements on Er 162 as a probe of statistical model calculations
It is crucial to measure reaction cross sections relevant to the astrophysical γ process so that theoretical reaction rates can be tested and validated with experimental data. The total cross
