Reaction models in nuclear astrophysics [PDF]
EPJ Web of Conferences, 2016 We present different reaction models commonly used in nuclear astrophysics, in particular for the nucleosynthesis of light elements. Pioneering works were performed within the potential model, where the internal structure of the colliding nuclei is ...

Towards More Predictive Nuclear Reaction Modelling
Springer Proceedings in Physics, 2021 Nuclear reaction modelling relies on three main theoretical models connected together, namely the optical model, the pre-equilibrium model and the compound nucleus model. Each of these models makes use of various input data, which can either be directly obtained from experiment or from experimentally-based systematics, fine-tuned to reproduce data of ...

Dependence of X-Ray Burst Models on Nuclear Reaction Rates
Astrophysical Journal, 2016 X-ray bursts are thermonuclear flashes on the surface of accreting neutron stars and reliable burst models are needed to interpret observations in terms of properties of the neutron star and the binary system. We investigate the dependence of X-ray burst

Towards many-body based nuclear reaction modelling [PDF]
EPJ Web of Conferences, 2016 The increasing need for cross sections far from the valley of stability poses a challenge for nuclear reaction models. So far, predictions of cross sections have relied on more or less phenomenological approaches, depending on parameters adjusted to ...

MEASUREMENT OF 182,184,186W (N, N’ γ) CROSS SECTIONS AND WHAT WE CAN LEARN FROM IT [PDF]
EPJ Web of Conferences, 2021 Today’s development of nuclear installations rely on numerical simulation for which the main input are evaluated nuclear data. Inelastic neutron scattering (n, xn) is a reaction of importance because it modifies the neutron population, the neutron energy

Improving nuclear data evaluations with predictive reaction theory and indirect measurements [PDF]
EPJ Web of Conferences, 2023 Nuclear reaction data required for astrophysics and applications is incomplete, as not all nuclear reactions can be measured or reliably predicted. Neutron-induced reactions involving unstable targets are particularly challenging, but often critical for ...

Low energy reactions of halo nuclei [PDF]
EPJ Web of Conferences, 2021 Halo nuclei are extreme nuclear states consisting of one or more weakly-bound valence nucleons spatially decoupled from a tightly bound nuclear core.

Shell-Model Treatment of Nuclear Reactions [PDF]
Physical Review, 1965 A method is developed for the calculation of resonant nuclear states which preserves as many features of the shell model as possible. It is an extension of the R-matrix theory. The necessary formulas are derived and a detailed description of the computational procedure is given. The method is valid up to the two-particle emission threshold.

TALYS: modeling of nuclear reactions
The European Physical Journal A, 2023 TALYS is a software package for the simulation of nuclear reactions below 200 MeV. It is used worldwide for the analysis and prediction of nuclear reactions and is based on state-of-art nuclear structure and nuclear reaction models. A general overview of the implemented physics and capabilities of TALYS is given. The general nuclear reaction mechanisms
