Microscopic modeling of direct pre-equilibrium emission from neutron induced reactions on even and odd actinides

open access: yesEPJ Web of Conferences, 2017
Direct inelastic scattering to discrete excitations and pre-equilibrium emission are described within a microscopic model. Nuclear structure information are obtained in the (Quasi) Random Phase Approximation ((Q)RPA) framework implemented with the Gogny ...

Development of a Shock and Detonation Velocity Measurement System Using Chirped Fiber Bragg Gratings

open access: yesSensors, 2020
Dynamic measurements of shock and detonation velocities are performed using long chirped fiber Bragg gratings (CFBGs). Such thin probes, with a diameter of typically 125 µm or even 80 µm can be directly inserted into high-explosive (HE) samples

Metastable water at several compression rates and its freezing kinetics into ice VII

open access: yesNature Communications
Water can be dynamically over-compressed well into the stability field of ice VII. Whether water then transforms into ice VII, vitreous ice or a metastable novel crystalline phase remained uncertain.

Ideas and Tools for Error Detection in Opacity Databases

open access: yesAtoms, 2023
In this article, we propose several ideas and tools in order to check the reliability of radiative opacity and atomic physics databases. We first emphasize that it can be useful to verify that mathematical inequalities, which impose lower and upper ...

Microscopic predictions of fission yields based on the time dependent GCM formalism

open access: yesEPJ Web of Conferences, 2016
Accurate knowledge of fission fragment yields is an essential ingredient of numerous applications ranging from the formation of elements in the r-process to fuel cycle optimization in nuclear energy.

Detailed Opacity Calculations for Astrophysical Applications

open access: yesAtoms, 2017
Nowadays, several opacity codes are able to provide data for stellar structure models, but the computed opacities may show significant differences. In this work, we present state-of-the-art precise spectral opacity calculations, illustrated by stellar ...

Absorption measurement of layers or materials: How to calibrate?

open access: yesResults in Physics, 2019
The knowledge of the absorption in the optical materials is important because it can generate problematic phenomena (distortion, depolarization, damage…) when high-power lasers are used.

A study on the rearrangement corrections to the folding model applied to nucleon inelastic scattering

open access: yesEPJ Web of Conferences, 2016
A study of direct neutron induced reactions off spherical nuclei is given in terms of a folding model. Matter densities stemming from the Random Phase Approximation (RPA), implemented with the Gogny D1S force are used to provide the relevant coupling ...
