S.P. : Proceedings of the Symposium on Mechanics for Space Flight}, month = {Mar}, note = {The relaxations of the velocity distribution and temperature of electrons cooled or heated by the rotational excitation or de-excitation of nitrogen molecules are studied using the Monte Carlo simulation in the system where the electrons with the initial temperature T_e (0) are diluted in the heat-bath molecules with the temperature T [100 ≤ T, T_e (0) ≤ 3000 K] and the rotational transition cross section is given by the Gerjuoy-Stein formula. The initial Maxwell electron velocity distribution is perturbed considerably in the cooling process and slightly in the heating process. The electron temperature is higher in the cooling process and lower in the heating process than that of Mentzoni and Row for the local Maxwell distribution. The temperature equilibration time is larger than that of Mentzoni and Row to the extent of about 25%. The initial δ-function electron velocity distribution approaches the Maxwell distribution through the rotational excitation and de-excitation only. The Max-wellization is much faster than the temperature equilibration., 資料番号: SA0033411000}, pages = {141--149}, title = {Relaxation of Velocity Distrbution of Electrons Cooled (Heated) by Rotational Excitation (De-excitation) of N_2}, volume = {1}, year = {1983} }
