Localization lengths, fluctuations of the conductance, and the density of states are computed for quasi-one-dimensional geometry. Numerical results indicate that the model exhibits the same critical behavior as the one studied by Gade and Wegner. It is argued that all the states except a zero-energy state are localized and the density of states has a singularity in the center of the band. The energy scale below which the density of states increases is found to be extremely small.4 pages, 5 figures, extensive revision made, but no change in conclusionMesoscale and Nanoscale PhysicsDisordered Systems and Neural Networkstext
