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). Reaction rates for γ-process reaction network studies have to be predicted using Hauser–Feshbach statistical model calculations. Recent investigations have shown problems in the prediction of α-widths at astrophysical energies which are an essential input for the statistical model. It has an impact on…

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.

Background: $\ensuremath{\alpha}$-nucleus optical potentials are basic ingredients of statistical model calculations used in nucleosynthesis simulations. While the nucleon+nucleus optical potential
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 $$^{154}$$

In 2008 a Starting Grant project supported by the European Research Council titled “Nuclear reaction studies relevant to the astrophysical p-process nucleosynthesis" was launched. After five years of
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

Solution of the α-potential mystery in the γ process and its impact on the Nd/Sm ratio in meteorites.
Since Coulomb excitation does not affect α emission, the 148Gd(γ,α) rate is much higher than previously assumed, which leads to very small 146Sm/144Sm stellar production ratios, in even more pronounced conflict with the meteorite data.

Beyond Fe, there is a class of 35 proton-rich nuclides, between 74Se and 196Hg, called p-nuclei. They are bypassed by the s and r neutron capture processes and are typically 10–1000 times less
The P-Process in a Realistic Supernova Model
The astrophysically most plausible site for the synthesis of the (Z ≥ 34) neutron deficient isotopes (the “p-nuclei”) seems to be the deep interior of highly evolved massive stars. There, (γ, n.)
