Abstract

If once the transport coefficientsσ(T) andκ(T)as functions of temperature are evaluated from the characteristic- and temperature measurements on an arc discharge, these results can be further reduced to the various cross sections involved in the related collision processes by means of the kinetic theory. For this purpose formulas are derived for the material functionsσ andκ which are still clear enough in their dependence on the different cross sections to be evaluated, and which on the other hand do not deviate too strongly from the exact solutions. As an example for nitrogen the collision cross sections which are effective in the temperature range 5500 ‡K≦T≦15500 ‡K are evaluated from measurements on an arc discharge.
