Abstract
The electron swarm parameters in Hg/Ar mixtures, which are important in connection with making Hg discharge lamps, are analysed using a Boltzmann equation in which Penning and cumulative ionizations are properly taken into consideration. This method is shown to be appropriate, since the present Townsend ionization coefficients are in good agreement with the experimental values of Burgmans et al over almost the whole range of E/P0 and ratio of the Hg to the total atom concentrations K where the experiments were carried out. The range of E/P0 where Penning, cumulative or direct impact ionization is dominant is quantitatively shown. The excitation coefficient for the 63p1 level of Hg from which 253.7 nm light radiates is obtained as a function of E/P0 and K, and is discussed in connection with the output of luminous flux of fluorescent discharge lamps.
