The model based on the exchange of the Pomeron as a pair of non-pert urbative gluons is modified to include the frozen coupling constant in the infra red kinematic region. A good fit to the data of the differential cross section f or different center of mass energies (53 GeV and 1.8 TeV) is obtained.REVTEX, 13 pages, 4 figuresHigh Energy Physics - Phenomenologytext
