We prove the existence of a three dimensional potential, UR(r), whose S-wave scattering amplitude has the complex zeros of the Riemann Zeta function as "redundant poles." The potential is a C" function on O<r < co, and JR r lUR(r)I exp(ar)dr < co, for O<a<21,, where Ai is the ordinate of the first z
