Connection between Regge-Pole and Single-Particle Exchange Models for High-Energy Reactions

It is shown that the $s^{\alpha \mathrm{}\left(0\right)\mathrm{}}$ energy dependence of high-energy transition amplitudes characteristic of the Regge-pole model can be obtained directly in the $s$ channel by summing the most divergent terms resulting from an infinite set of single-particle exchanges in the $t$ channel.
