Abstract
A weakly disordered quasi-one-dimensional tight-binding hopping model with rows is considered. The probability distribution of the Landauer conductance is calculated exactly in the middle of the band, where , and it is shown that a delocalization transition at this energy takes place if and only if is odd. This even-odd effect is explained by level repulsion of the transmission eigenvalues.
