Uncertainties in adopted models of particle+nucleus optical-model potentials directly influence the accuracy in the theoretical predictions of reaction rates as they are needed for reaction-network calculations in, for instance, {\gamma}-process nucleosynthesis. The improvement of the {\alpha}+nucleus optical-model potential is hampered by the lack of experimental data at astrophysically relevant energies especially for heavier nuclei. Measuring the Re187({\alpha},n)Ir190 reaction cross section…

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.

The cross section calculation of 112Sn(α,γ)116Te reaction with different nuclear models at the astrophysical energy range

The theoretical cross section calculations for the astrophysical p process are needed because most of the related reactions are technically very difficult to be measured in the laboratory. Even if

Role of consistent parameter sets in an assessment of the α -particle optical potential below the Coulomb barrier

Background: Further studies of high-precision measurements of alpha-induced reaction data below the Coulomb barrier have still raised questions about the alpha-particle optical model potential (OMP)

α -induced reactions on 115 In: Cross section measurements and statistical model analysis

Background: $\ensuremath{\alpha}$-nucleus optical potentials are basic ingredients of statistical model calculations used in nucleosynthesis simulations. While the nucleon+nucleus optical potential

γ-process reaction studies via in-beam γ-ray spectroscopy at HORUS

The predictions for reaction rates from the Hauser-Feshbach statistical model as they are needed for γ-process reaction-network calculations crucially depend on the accuracy of the nuclear physics

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

Uncertainties of α-particle optical potential assessment around and below the Coulomb barrier

A competition of the low-energy Coulomb excitation (CE) with the compound nucleus (CN) formation in α-induced reactions below the Coulomb barrier has recently been assumed in order to make possible

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
