Elerctron Transport Coefficients in N2 in Crossed Fields at Low E/p

The numerical solutions of Boltzmann transpott equation for the energy distribution of electrons moving in crossed fields in nitrogen have been obtained for 100 ≤ E/p ≤ 1000 V M-1 Torr-1 and for 0≤ B/p ≤ 0.02 Tesla Torr-1 using the concept of energy dependent effective field intensity. From the derived distribution functions the electron mean energy, the tranaverse and perpendicular drift velocities and the averaged effective field intensity (Eavef) which signifies the average field intensity experienced by electron swarms in E × B field have been derived. The maximum difference between the electron mean energy for a given E × B field and that corresponding to Eavef/p (p is the gas pressure) is found to be within ±3.5%.
