Query: Proton-Proton On Shell Optical Potential at High Energies and the
  Hollownes Effect   We analyze the usefulness of the optical potential as suggested by the double
spectral Mandelstam representation at very high energies, such as in the
proton-proton scattering at ISR and the LHC. Its particular meaning regarding
the interpretation of the scattering data up to the maximum available measured
energies is discussed. Our analysis reconstructs 3D dynamics from the effective
transverse 2D impact parameter representation and suggests that besides the
onset of gray nucleons at the LHC there appears an inelasticity depletion
(hollowness) which precludes convolution models at the attometer scale.
