### Abstract

For pt.I see ibid., vol.17, p.699 (1984). An investigation of the deep structure of the electron diffusion tensor D in an isolated swarm has been developed from the Boltzmann equation as applied to the electron conservative case including inelastic collisions. It is shown that D consists of three components. They are the weighted ensemble average in the velocity space, and the two-additional terms which represent both the curvature effect due to the electric field and the scattering effect at collision. Numerical calculations in Ar have been executed to emphasise the importance of the last two terms. A difference of over 5% appears between the transverse diffusion coefficient D_{T} and the conventional expression D_{V} with E/N subject purely to elastic collisions due to the curvature effect. As is expected, the discrepancy between D_{T} and D_{V} grows with E/N where the recycling effect due to the excitation-energy barrier is included.
