- The CCC method
yields accurate excitation and ionisation cross sections for
atomic and ionic targets which are well-modelled by one or two
valence electrons above a Hartree-Fock core.
- Inner core ionisation can be a major contributor to the total
ionisation cross section. Such contributions can be estimated using
various forms of Born-based approximations. Contact me at I.Bray@curtin.edu.au for details.
