Abstract
In this article I give an iteractive scheme to compute the coefficients of the power series expansion in the electric field parameter of the Stark-Wannier states in one-dimensional crystals. For symmetric crystals the asymptotic expansion up to the fourth order is explicitly computed, and for a solvable model the method is verified up to any order.
