Effect of electronic excited states on transport in magnetized hydrogen plasma

Multicomponent diffusion coefficients for magnetized, equilibrium hydrogen plasma have been calculated. The equilibrium composition of the plasma is determined by taking consistently into account the number of allowed atomic electronic excited states (EES) as determined by the average interparticle distance. The coefficients are shown to depend on the inclusion of realistic cross sections for the interactions with EES. The effect of an applied magnetic field on the diffusion coefficients and on derived quantities like the electrical conductivity and the internal and reactive thermal conductivity is studied and explained.(c) 2007 American Institute of Physics.
