Peek, J M

The creation of inner-shell vacancies can play an important role in the transport of and energy deposition by fast incident particles. Most high-energy electron-transport models include this phenomenology. A large body of cross-section data is available for this purpose, but many gaps remain to be filled by interpolation or extrapolation methods. The published data become more sparse as the energy of the incident particle becomes relativistic and the nuclear charge of the target becomes large. The use of relativistic Bethe-Born theory for inelastic electron scattering to augment the existing data for inner shell vacancy production is described. The data required to implement this technique have been calculated with both a Hartree-Fock and a relativistic Hartree-Fock description used to define the target structure. The resulting cross sections are available for most elements and for most of their orbitals if the valence electrons are excluded. Comparisons of these data with existing experimental and theoretical inner-shell ionization information are summarized.
