From self-consistent determination of the dynamical diffusion coefficient, theFermi energy dependence of the localization length, I,(E.), is obtained for thecase where the Fermi energy, E., lies near the center of the lowest Landau sub-band. If the energy is measured from the point where the real part of the retardedGreen's function vanishes, :(E.) for small lE.l is expected to be proportional tol exp (7'/Ej) with l the cyclotron radius and 7 a constant of the order of subbandwidth.
