An extensive effort was put together
by Ponomarev and his colleagues to perform the task of truly multi-level
calculations in the Adiabatic Representation [99]. The results
for scattering on a bare nucleus have been published in an atlas of cross
sections, referred in this thesis as the ``Nuclear
Atlas'' [16,17,18]. The accuracy for the purely
three-body problems (*i.e.*, atomic and molecular effects ignored) is claimed
to be % [24]. For a recent review of multi-level
calculations and a comparison with other methods,
