  We have confirmed and complemented previous conclusions from studies of the
impact parameter profiles, relative to $pp$ and $\bar pp$ scattering, using a
generalized eikonalized amplitude. In particular, the transition from the grey
to the black disk is followed, when the energy increases beyond $\sim 3$ TeV
and for the inelastic process, by a black ring surrounding the antishadow
scattering mode at the center. The ranges of hadronic forces responsible for
the elastic and inelastic processes are estimated by means of root-mean-squares
of the impact parameter. Predictions at the LHC energy are explicitly given.
The effect of eikonalization is discussed.
