Collision integrals of electronically excited states and transport coefficients of thermal plasmas

Abstract

Collision integrals of excited hydrogen atoms were calculated in the temperature range 10000–25 000 ˚K. These values were used for calculating the viscosity and έ the contribution of the heavy components λ_H to the translational thermal conductivity of a LTE hydrogen plasma. The results show a dependence of έ and λ_H on the calculated transport cross-sections.
