【 摘 要 】

We consider conditions of strong Langmuir turbulence, for which a wave packet cycle is observed. The dynamics of such intense Langmuir electric fields may affect the line broadening of simple atoms. We use a simple stochastic model to evaluate the effect of such turbulent fields on the Lyman α line in low density plasmas.
