Description of a system of interacting linear chains by means of the electron network model

Abstract
The electron network model of Coulson and Della Riccia is applied to describe a simple lattice consisting of two families of linear chains, coupled together. It is shown that the model displays resonances, at which the wavefunction is preferentially situated at one or the other family of chains, and that at these resonances, there is a 1/√E divergence in the electronic density of states.
