abstract
We present a two channel eikonal calculation in which the rescattering through a diffractive channel is included in addition to the elastic channel. Considering the spread of the experimental data, we find that we can obtain a very good description of $\s_{tot}$, $\s_{el}$ and $B_{el}$ in the ISR - Tevatron energy range. In this range of energy the diffractive channel, that was included in our calculation, leads to a ratio of $\s_{SD}/\s_{el}$ which varies between 1 and 0.5 for $20 GeV \leq \sqrt{s} \leq 14 TeV$ in agreement with the experimental data. The calculated survival probability of dijet production with a large rapidity gap is consistent with the data.
