• The question of existence of unique and square integrable solutions of the Lippmann-Schwinger equation is examined for a class of seoarable non-local potentials. A simple procedure is given to obtain the equivalent potentials. The behaviour of the scattering wave function for the non-local separable potentials is compared with the same fot a class of local potentials. The S-matrix is constructed for non-local separable potentials with Yukawa and Gaussian type r(r') dependence and their properties are investigated in both momentum (k) and angular momentum (l) planes. It is found that important analytical properties of the S-matrix for these non-lacal potentials are similar to those obtained in the case of corresponding local potentials, namel Yukawa and Gaussian potentials.
