Current Status and Developments of the Atomic Database on Rare-Earths at Mons University (DREAM)

open access: yesAtoms, 2020
The main purpose of the Database on Rare Earths At Mons University (DREAM) is to provide the scientific community with updated spectroscopic parameters related to lanthanide atoms (Z = 57–71) in their lowest ionization stages.

Stark broadening parameter tables for Ar VIII [PDF]

open access: yesSerbian Astronomical Journal, 1999
Using a semiclassical approach, we have calculated electron−, proton−, and He III−impact line widths and shifts for 9 Ar VIII transitions as a function of temperature and perturber density.

Use of the ESI-2007 scale to evaluate the 2003 Boumerdès earthquake (North Algeria)

open access: yesAnnals of Geophysics, 2016
In this study, we applied the environmental seismic intensity (ESI-2007) scale to a major recent Algerian earthquake. The ESI-2007 scale is an effective tool to assess the seismic hazard and has been applied to onshore earthquakes.

La physique nucléaire en astrophysique [PDF]

open access: yesAnnales de Physique, 2001
L'astrophysique nucleaire est sans nul doute l'une des branches les plus largement interdisciplinaires de la science et est intimement connectee a une tres grande variete d'autres domaines de recherche. Cet ouvrage se limite a une breve presentation des relations privilegiees qui se sont etablies entre l'astrophysique et la physique nucleaire.
