Cutoff criteria of electronic partition functions and transport properties of atomic hydrogen thermal plasmas

Transport coefficients of equilibrium hydrogen plasma have been calculated by using different cutoffs of electronic partition functions and different sets of transport cross sections of electronically excited states. The selection of both the cutoff criterion and transport cross sections deeply affects the transport coefficients of the H, H(+), e plasma mixture in the temperature range of 10 000-50 000 K and in the pressure interval of 1-1000 atm.
