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 the a-nucleus optical model potential. Several different parameter sets are available in literature, but their predictions of a-induced reaction rates vary widely, sometimes even exceeding one order of magnitude. This paper presents the result of a-induced reaction cross-section measurements on…

Successful Prediction of Total α-Induced Reaction Cross Sections at Astrophysically Relevant Sub-Coulomb Energies Using a Novel Approach.

TLDR
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.

Activation measurement of a-induced cross sections for 197Au: analysis in the statistical model and beyond

Cross sections of ( α,γ), (α,n), and (α,2n) reactions for 197Au were measured below the Coulomb barrier using the activation technique. The new data are analyzed in the statistical model and in a

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

Constraining nuclear properties in Mo94 via a Nb93(p,γ)Mo94 total cross section measurement

Background: The nucleosynthesis of the group of neutron-deficient $p$ nuclei remains an unsolved puzzle in nuclear astrophysics. Among these nuclei, $^{94}\mathrm{Mo}$ is one of the most abundant and

In experimental nuclear astrophysics it is common knowledge that reaction cross sections must be measured in the astrophysically relevant, low energy ranges or at least as close to them as possible.

New measurement of the Sm144(α,γ)Gd148 reaction rate for the γ process

Background: Most of the heavier $p$ isotopes are believed to be produced in the $\ensuremath{\gamma}$ process whose reaction path crucially depends on the proton and $\ensuremath{\alpha}$-particle

Examination of $$\alpha $$-induced fusion reactions relevant to the production of p-nuclei

The present paper examines the effect of temperature-dependent repulsive core potential on the fusion reactions of the $$\alpha $$ particle relevant to the production of p-nuclei such as $$^{154}$$
