A theory of electron scattering by pcvtential witlt slow spatial variation in onedimensional systems: is proposed. It takes into account the perturbation of all ordertaking advantage of tlte long range nature of the potential. The theory is extended tothe case of random pc>tential and good agreenxents w'ith the numerical calculation arcobtained for wide range of parameters, while the precision of Born approximationbecomes rapidly worse if the correlation length of' the potential exceeds the wavelength of the electron. As an application, the naobility of quantum wires limited bythe surface roughness scattering is discussed.
