Redistribution of resonance radiation in hot and dense plasmas

The development of a numerical procedure for the study of the resonant two photon plasma spectral properties is presented. The formalism is based on an extension of the Frequency Fluctuation Model (F.F.M.) that permits the calculation of the spectral line shape of Stark broadened lines emitted by multi-electrons ions and takes into account ion dynamics effect. We present an application for the study of resonant scattering by a calculation of the radiative redistribution function for the 3d-2p transition of MgIV.
