 Title: Production and decay of Sulphur excited species in a ECRIS plasma Authors: Martins, Maria ConceiçãoMarques, José PiresCosta, Ana MariaSantos, José PauloParente, FernandoSchlesser, SophieLe Bigot, Eric-OlivierIndelicato, Paul Keywords: X-ray spectraECRISPlasmaTransition probabilities Issue Date: 2009 Publisher: American Physical Society Citation: Physical Review A: Atomic, Molecular and Optical Physics 80, 032501 (2009) Abstract: The most important processes for the creation of S12+ to S14+ ions excited states from the ground configurations of S9+ to S14+ ions in an electron cyclotron resonance ion source, leading to the emission of K X-ray lines, are studied. Theoretical values for inner-shell excitation and ionization cross sections, including double KL and triple KLL ionization, transition probabilities and energies for the deexcitation processes, are 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 is obtained, which is compared to recent experimental data.
