摘要：

The most important processes for the creation of chlorine ion excited states from the ground configurations of Cl10+ to Cl15+ ions in an electron cyclotron resonance ion source, leading to the emission of K x-ray lines, were studied. Theoretical values for inner-shell excitation and ionization cross-sections, including double KL and triple KLL ionization, transition probabilities and energies for the de-excitation processes, were calculated in the framework of the multi-configuration Dirac-Fock method. With reasonable assumptions about the electron energy distribution, a theoretical K alpha x-ray spectrum was obtained, which was then compared with recent experimental data.
