Theoretical investigations of charge exchange and
ionization processes accompanying collisions of negative and
positive atomic ions are reviewed. Detailed analysis of the
Coulomb Green function provides vast information about these
processes. In particular, we took previously unknown sums of
Coulomb wave function products over degenerate states. Adiabatic energies of the system and its wave functions can be
expressed through these sums, whereas the wave functions turn
out to possess very interesting and unexpected properties.
