The analytical formulae for the two kinds of RMFP have been given, by which the RMFP have been calculated for the interesting small atomic number Z. The calculated results show that the RMFP in non local thermal equilibrium (non LTE) and in LTE are obviously different and Planck RMFP is 30 times less than Rosseland one.
