Asymptotic normalization coefficients in nuclear reactions and nuclear astrophysics

, 2022
The asymptotic normalization coefficient (ANC) is a fundamental nuclear characteristic of bound states and resonances. The ANC plays an important role in low-energy elastic scattering, transfer and radiative capture reactions, and provides a powerful ...

Capturing Thermal Effects Beyond the Zero‐Temperature Approximation Using the Uniform Electron Gas

Contributions to Plasma Physics, EarlyView.
ABSTRACT Density functional theory at finite temperatures often relies on the zero‐temperature approximation, which uses a ground‐state exchange‐correlation functional with thermalized densities. This approach, however, neglects the explicit temperature dependence of the exchange‐correlation free energy—a key factor in regimes such as warm dense matter,

Nuclear Problems in Astrophysics

Proceedings of the International School of Physics “Enrico Fermi”, 2003
These lectures, presented at the International School of Physics ``Enrico Fermi,'' deal with two major themes. The first is the remarkable story of the solar neutrino problem, which (along with the atmospheric neutrino anomaly) recently led to the discovery of massive neutrinos and neutrino oscillations, physics beyond the standard model.

Transfer reactions for nuclear astrophysics

EPJ Web of Conferences, 2018
Direct measurements of cross sections at stellar energies are very challenging - if at all possible. This is essentially due to the very low cross-sections of the reactions of interest (especially when it involves charged particles), and/or to the ...

Magneto‐Electrochemical Effect on La‐Doped GaFeO3 as a Supercapacitor Electrode for Energy Storage

Electron, EarlyView.
The electrochemical performance of La‐doped Gallium Ferrite (La‐doped GaFeO3 ${\text{GaFeO}}_{3}$) synthesizes via a conventional solid‐state reaction method; this has been studied by the application of an external magnetic fields. ABSTRACT The electrochemical performance of La‐doped GaFeO3 ${\text{GaFeO}}_{3}$ synthesizes via a conventional solid ...

Photoneutron Reactions in Nuclear Astrophysics [PDF]

Journal of Physics: Conference Series, 2015
Highly-monochromatic γ-ray beams are produced at the NewSUBARU synchrotron radiation facility by the inverse Compton scattering of laser photons from relativistic electrons. The latest s-process study in nuclear astrophysics with the γ-ray beam is presented.

Reactor neutrons in nuclear astrophysics

EPJ Web of Conferences, 2017
The huge neutron fluxes offer the possibility to use research reactors to produce isotopes of interest, which can be investigated afterwards. An example is the half-lives of long-lived isotopes like 129I.

Nuclear physics -a driving force of the Universe [PDF]

EPJ Web of Conferences
The origins of the elements in the Universe are the overarching research goal in nuclear astrophysics. The light elements have been produced in the first minutes after the Big Bang, while the other elements are synthesized by nuclear reactions occuring ...
