RT info:eu-repo/semantics/article T1 Calculations of the polarization spectrum by two-photon absorption in the hydrogen Lyman-α line A1 Gigosos, Marco Antonio A1 González, Manuel Ángel AB We present calculations, obtained by computer simulation, of the polarization spectrum by two-photonabsorption in the transition 1S→2S of hydrogen in plasmas at low electronic density. Fine structure and iondynamic effects have been included. The obtained results allow one to make a map of linewidths as a function of the electronic density and temperature to be applied for diagnosis in plasmas.
