“…There is a possibility that the reason for the discrepancies between the values of figure 2 and those by Brooks et a1 (1982) is the time resolution of the detection system they used. The calculated values of W of Lehrke and Muller (1976) and Makabe and Mori (1978) are about 35% smaller than the present calculated results at E/N = 100 Td. These discrepancies are due to their use of unsuitable cross-sections, especially large values of qm for electron energies larger than 5 eV.…”

“…At 120 < E/N < 300 Td, the present calculated values coincide with the experimental values of Wagner (1964). The present calculated values were extrapolated smoothly to the experimental values at low E/N (-10 Td) of Bowe (1960) (0) Wagner (1964); ( 0 ) Makabe and Mori (1978). Theory: (-----) Lehrke and Muller and Phelps (1962).…”

“…The values of mean electron energy ( E ) were calculated as a function of distance from the cathode, as shown in figure 8 under equilibrium conditions and the mean energy at the anode ( E ~) are shown in figure 6, along with other calculated results of Lehrke and Muller (1976) and Makabe and Mori (1978). The values of ( E ) are also shown in table 3.…”

“…However, the values of ( E ) are rather insensitive to the values of q m , so the difference between the present calculated results and those of other authors are smaller than those of W or DT/p. The three points indicated by + symbols in figure 6 are the experimental values of Makabe and Mori (1978) obtained by the measurement of the energy distribution functions using the retarding potential method. The experiment is very difficult and the results obtained from the method using a hole in the anode require a difficult correction due to a non-equilibrium region in front of the anode.…”

Swarm parameters (electron drift velocities, ratios of electron radial diffusion coefficient to mobility, mean electron energies and electron energy distribution functions) have been calculated in xenon by a Monte Carlo simulation method Values of these parameters have been obtained for ratios of the electric field to the gas number density E/N from 85 to 8500 Td (E/p0=30 approximately 3000 V cm-1 Torr-1 at 0 degrees C). Calculated results were compared with available experimental and other calculated data. Calculations relating to the non-equilibrium distance d0 in front of the cathode and non-equilibrium distance near the anode were also carried out. For these calculations, elastic momentum transfer cross-sections and inelastic cross-sections up to 104 eV reported in the author's preceding paper (see ibid., vol.16, p.581-9, 1983) were used.

“…Huxley and Crompton 1974). Some efforts have been directed to the corresponding experimental analysis (Kenny and Craggs 1970, Losee and Burch 1972, Makabe and Mori 1978. Some further theoretical developments have been reported recently to exhibit the anisotropic velocity distribution function (Kitamori et al 1978, Makabe andMori 1980).…”

The theoretical analysis of the velocity distribution function of ions in weakly ionised gases is developed under the condition of induced dipole interaction between ion and molecule by using the BGK approximation in the Boltzmann equation. The derived functions is valid for arbitrary reduced field strength E/N and ion-neutral mass ratio m/M. The results are compared with the previous works of Whealton and Woo (1971), and Wannier (1958), and it is found that predicted distribution function exhibits great power in the case of nearly the same mass. Also the anisotropy of the distribution function is investigated.
