A separable representation of the Paris potential is constructed by means of the Ernst-Shakin-Thaler method. The resulting separable interactions represent a good approximation of the on-shell as well as off-shell properties of the Paris potential. Their form factors are composed of rational functions not too complicated for today's computer codes for few-body systems. The various features of the nucleon-nucleon force are discussed together with first results obtained with these separable potentials for elastic electron-deuteron and nucleon-deuteron scattering.
