FAST NUMERICAL-METHODS FOR LINE-SHAPE STUDIES IN HOT AND DENSE-PLASMAS

For hot and dense plasma studies both fundamental or diagnosis oriente d, one needs to solve concurrently several problems coming from differ ent fields. Our contribution to such studies has been to develop a fas t computer code capable of providing spectral profiles for the radiati on emitted by multiply charged ions imbedded in hot and dense non-equi librium plasmas. The results of this numerical method have been carefu lly compared to those generated by a simulation code based on a molecu lar dynamic simulation of the stochastic microfield. This paper provid es information about some new aspects of the line mixing model used to account for the ion dynamic effect in a very fast way.
