Opacity predictions in plasmas under stellar conditions using deep learning

Djamel Benredjem, Jean-Christophe Pain

The aim of this work is to predict the opacity of plasmas under stellar conditions. We focus on iron and nickel, as these elements have been extensively investigated both theoretic…

Excitation and ionization by electron impact in transition and super-transition arrays

Djamel Benredjem, Jean-Christophe Pain

This study investigates the ionization and excitation processes induced by electron impact between two configurations or superconfigurations. Rate coefficients are calculated for t…

Corrections to radiative rates between atomic configurations

Jean-Christophe Pain, Djamel Benredjem

The computation of radiative opacity or emissivity of hot dense matter is a challenging task. It requires accounting for an immense number of energy levels and lines across various…

A new approach to include electron interaction effects in super transition array opacity theory

Daniel Aberg, Brian G. Wilson, Jean-Christophe Pain

A method is presented for the improved calculation of super-shell partition functions which include the repulsive electron-electron interaction energy terms in the Boltzmann factor…

Electron-impact ionization of Si IV-VIII relevant for inertial confinement fusion

Jean-Christophe Pain, Djamel Benredjem

In this work, we investigate the ionization of silicon by electron impacts in hot plasmas. Our calculations of the cross sections and rates rely on the Coulomb-Born-Exchange, Binar…

Benford's law in atomic spectra and opacity databases

Jean-Christophe Pain, Yuri Ralchenko

The intriguing law of anomalous numbers, also named Benford's law, states that the significant digits of data follow a logarithmic distribution favoring the smallest values. In thi…
