Short distance Regge singulaities are defined. Potentials of the form V(r) = G(r)r-2 with G(r) ≃a/log
r0/r are used in order to simulate characteristic short distance singularities of asymptotically free field theories. The existence of an accumulation point of complex Regge poles at l = -(1/2) is established for repulsive and attractive potentials. The relevance of the Schrödinger theory results for the problem of the bare Pomeron is discussed briefly.
