Abstract
The sharp forward electron-phonon (FEP) and impurity (FIS) scattering chang e the normal and superconducting properties significantly. The pseudo-gap l ike features are present in the density of states for omega < Omega, where Omega is the phonon frequency. The superconducting critical temperature T-c , due to the FEP pairing, is linear with respect to the electron-phonon cou pling constant. The FIS impurities are pair weakening for s- and d-wave pai ring.
