Does plasma structure influence molecule formation and radiation characteristics?

In this presentation several consequences of the plasma state with spatial structures will be discussed. The basic thought is that a concentration of neutral hydrogen gas in combination with weak magnetic fields will cause elongated plasmas with higher density, which will expand along the field lines. As a consequence the plasma is more concentrated in filamentary structures, the charge density is higher and electron temperature can be higher as well. Clusters will be more charged, which will influence the transport of radicals and charge. The electron density life time may not be limited by dissociative recombination. A comparison is made of the effects of such a stratified medium as compared to a homogeneous plasma for dark clouds conditions. The effect of a structured medium could be that more radicals (as H) are formed and more molecules are formed. Also finite fields and currents may have influence on plasma kinetics.Ope
