Checking the reliability of opacity databases [PDF]

open access: yes, 2023
Mathematical inequalities, combined with atomic-physics sum rules, enable one to derive lower and upper bounds for the Rosseland and/or Planck mean opacities. The resulting constraints must be satisfied, either for pure elements or mixtures.

Atomic properties in hot plasmas: from levels to superconfigurations [PDF]

open access: yes, 2015
This book is devoted to the calculation of hot-plasma properties which generally requires a huge number of atomic data. It is the first book that combines information on the details of the basic atomic physics and its application to atomic spectroscopy ...

Sur la physique atomique des ions dans les plasmas en présence de l'écrantage [PDF]

open access: yes, 2002
This work is an improvement of the characterisation of ionic species in plasmas. It is important to model the thermodynamics of these plasmas, especially in order to describe their ability to absorb radiations.

Spectroscopie d'absorption X résolue en temps pour l'étude de la matière dense et tiède [PDF]

open access: yes, 2009
The possibility of producing, in a controlled way, matter at solid density (1-10 g/cc) while maintaining it at temperatures ranging from 0.1 to 100 eV has been for a long time a desired goal.
