Long-term-averaged three-dimensional data-based models were made of the -30 < x < -10, ∣y∣ < 15, ∣z∣ < 5 RE plasma sheet region. The average magnetic moments $langle$¿$rangle$ and Chew-Goldberger-Low (CGL) double adiabatic parameters α$perp$ and α$parallel$ were evaluated for ions and electrons. It was shown that restricting the observations to those taken within 0.2 RE of the Bx = 0 point gave both a good determination of conditions at the neutral sheet and enough data points for reliable averages. Large pitch angle anisotropies would develop if the CGL parameters were constant along drift paths. In contrast, pitch angle scattering was so rapid that the observed plasma remained almost isotropic and it was the CGL parameters that varied markedly along the drift paths. Frequent ion scattering is explained by the chaotic nature of ion orbits, but electrons usually spiral around magnetic field lines even at the neutral sheet. Electron scattering by an average of 90¿ was needed during the 1 min it takes for a typical flux tube to undergo a net earthward displacement of 0.1 RE. A fast flow flux tube could move several Earth radii during this characteristic scattering time period. Rapid electron scattering also provides a mechanism to divert perpendicular current to form Birkeland current, produces diffusion, and generates a heat flux. The long-term-averaged magnetization vector M was evaluated and used to calculate the magnetization or bound current density jm = $nabla$ ¿ M. The magnetization current and an almost oppositely directed perpendicular free or guiding center drift current jf were strongest near the neutral sheet. Their sum, the total perpendicular current density j$perp$, was an order of magnitude smaller than either jm or jf in this region.
