Research Activity

Research Unit: LASER AND SPECTROSCOPY

Sub-group: PLASMA SPECTROSCOPY

My research activity is focused on plasma spectroscopy.
We study the light emitted from laboratories and stellar plasmas.
The modeling of the plasmas of neutral atoms, singly ionized and multicharged ions permits to make the diagnosis of such plasmas (determination of the temperature and the density of the plasma).
From the calculation of the profiles of spectral lines emitted by stars, one can deduce the characteristics of their atmospheres.
We calculate energy levels and oscillator strengths for atoms and ions.
We calculate also widths and shifts of lines emitted by a laboratory or astrophysical plasmas.
One of our new techniques is the study of line ratio which is a good diagnostic of plasmas.
