ArK x-ray production cross sections in collisions with highly ionized Cu at 50–70 MeV

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The projectile charge state dependence of ArK x-ray production in collisions with Cu11+ through Cu22+ions has been investigated at ∼1 MeV/amu. A distinct change in the behaviour of the cross section as a function of charge stateq was observed forq≧19 where CuL shell vacancies are brought into the collision. The assumption that the vacancy production is predominantly due to 2pσ-2pπ electron promotion via rotational coupling leads to a consistent description of the data.
