A method for measuring the electrical conductivity of cylindrical discharge plasmas in dependence of temperature and of pressure with appreciable accuracy has been developed. Results are given for T = 10000…12000 °K and p = 10 at and 20 at. Comparisons with calculations of Schirmer and Friedrich for partially ionized gases result in the proposal to cut off the interaction distance between charged particles at a 0 = 2 D instead of a 0 = D, where D is the Debye shielding parameter. With respect of the results the applicability of the Boltz‐mannequation and the Debye‐Hückel theory in the case of cold dense plasmas are discussed.
