  The sharp forward electron-phonon $(FEP)$ and impurity $(FIS)$ scattering
change the normal and superconducting properties significantly. The pseudo-gap
like 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
coupling constant. The $FIS$ impurities are pair weakening for $s-$ and
$d-wave$ pairing.
