Abstract
By suitably defining theK-matrix with only the two-particle cuts removed, we investigate its cut structure at high energy and show that it is not unreasonable to approximate this amplitude by single Reggepole exchange. It is also shown that the integral equation relating thisK-matrix to the fullT-matrix can be solved approximately at high energies giving a modified form of the absorption model. Thus we find a theoretical framework in which it is reasonable to apply absorptionlike corrections to a Regge-pole exchange amplitude.
