An overview of projectile-charge-state dependence of K-, L-, and M-shell ionization in thin solid targets for a variety of incident heavy ions up to 5.68 MeV/amu

This talk will summarize most of the experiments that have been done to study the charge state dependence of inner-shell ionization in the K, L, and M shells in the thin solid targets. A study of the charge state dependence under approximate single collision conditions can provide information in regard to the Electron Capture (EC) contribution to inner-shell ionization. The EC process is expected to be more profound at lower ion velocities, v1≤v2e and for Z1≤Z2 where Z1 and Z2 are the atomic numbers of the projectile and the target atom, and v1 and v2e are the velocities of the projectile ion and the target inner-shell electron, respectively. Extended data from the authors' own laboratory over a fairly large time span as well as a variety of papers in the open literature on similar studies for selected projectiles from Z1=5 to 17 will be summarized for incident ions in the range 0.1 to 5.68 MeV/amu. The experimental data will be compared to current Coulomb ionization theories
