Cross-sections for [Formula: see text]Ca + [Formula: see text] at low energies have been calculated from two different models and three different [Formula: see text]-nucleus potentials. The first model determines the cross-sections from the barrier transmission in a real nuclear potential. Second, cross-sections are derived within the optical model (OM) using a complex nuclear potential. The excitation functions from barrier transmission are smooth, whereas the excitation functions from the OM…

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

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.

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

Activation cross section measurement of the 100Mo(α,n)103Ru reaction for optical potential studies

The light neutron-rich nuclei can be synthesized via (α,n) reactions in the so-called weak r-process. The abundances of these species are derived using reaction network calculations. Such a

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

Background: α-nucleus potentials play an essential role for the calculation of α-induced reaction cross sections at low energies in the statistical model. Uncertainties of these calculations are

The cross section for the direct radiative capture of protons by 16O has been measured relative to the proton elastic scattering cross section for energies from 800 to 2400 keV (CM). The elastic

Systematic study of the α-optical potential via elastic scattering near the Z=50 region for p-process nuclei

Production of proton-rich nuclei beyond iron in stars proceeds via the p process, i.e., a sequence of photodisintegration reactions, (γ ,n), (γ ,p), and (γ ,α) on heavy nuclei at temperatures of 2–3

Investigation of Sub-Coulomb barrier fusion reaction of α +40Ca in different models

In this study, microscopic nucleon–nucleon Double Folding (DF) and phenomenological potentials have been used to investigate α +40Ca reaction observables at sub-barrier energies. In the calculations,

Molecular interpretation of the oscillations of the fusion excitation function for the alpha +40Ca system.

It is shown that the correct reproduction of the spacing between the fusion oscillationsmore is achieved, which results from the use of a deep real potential, which automatically yields a decoupling between positive and negative parity bands.
