Measurement of impact parameter dependent probabilities and total cross sections for targetK-shell ionization by He+ ions

  • Published:
Zeitschrift für Physik D Atoms, Molecules and Clusters

Abstract

We have measured the impact parameter dependent K-shell ionization probabilitiesP K (b) of Ca, Cr and Cu from collisions with 4.04 MeV He+ ions by particle-K X ray coincidences. A dependence on the target thickness was investigated to study a possible influence of multiple collisions onP K (b). We measured the total cross section σ K forK vacancy production simultaneously withP K (b) and σ K agrees within 30% with the integratedP K (b). A comparison of theP K (b) and σ K with SCA calculations of Trautmann et al. using RHFS wavefunctions for united atom and separated atom states is discussed.
