  We demonstrate a new method for the calculation of inelastic scattering
cross-section, which in contrary to the Regge-based methods takes into account
the energy momentum conservation law. By virtue of this method it was shown
that the main contribution to integral expressing inelastic scattering
cross-sections comes not from the multi-Regge domain. In particular this leads
to the fact that accounting of longitudinal momenta contribution to
virtualities is sufficient and results in the new mechanism of cross-section
growth. The necessity of taking into account the large number of interference
contributions is shown and the approximate method for this purpose is
developed. By considering the interference contributions from a single fitting
constant achieved a qualitative agreement of the total and inelastic cross
sections with experimental data.
