A separable approximation for the S01, P11, P03, and P13 channels of the N-N Reid soft core and Argonne potentials, based on the use of Gamow states, is presented. The on- and off-shell scattering amplitudes obtained from these separable forms are compared with the corresponding exact ones. Excellent agreement is obtained, which makes the Gamow separable approximation a successful and unambiguous method to construct separable approximations for local realistic N-N interactions.
