it is interesting to reexamine the “elastic” scattering analyses we described in Sec.3.1 to see if the proposed procedure to measure blackness is also destroyed by the dominance of gluons and quarks at higher $k_\perp$- values. Finally, it should be pointed out that there are already rather detailed calculations of the phenomenon, at least for $q\bar{q}$ and $q\bar{q}g$ components of the $\gamma^*$ wavefunction, which arrived at a value $n \approx
0.5,$ not too far from experiment\[8\]. Have we, for the first time, actually seen the long sought after evidence for nonlinearity (unitarity limits) in the semihard region of deep inelastic scattering?

Before leaving this section, it may be useful to again contrast hadron-hadron scattering with $\gamma^*$-proton scattering. In the purely hadronic case the energy dependence of the single diffraction cross section is much weaker than that predicted by the soft pomeron. We have interpreted this as due to blackness in central proton-proton collisions which enhances the elastic cross section but suppresses diffractive excitation. In $\gamma^*$-proton scattering, on the other hand, the energy dependence (x-dependence) is much stronger than that predicted by the soft pomeron. We have interpreted that also as due to blackness of the soft components of the $\gamma^*$
