Abstract

The effect of the atomic electronically excited states in the calculation of the transport properties of an hydrogen thermal plasmas in equilibrium conditions is investigated. The reactive thermal conductivity calculated by using appropriate diffusion cross sections for excited states shows strong differences with the corresponding results obtained by using ground state cross sections. The effect is well evident at high pressure.
