Auger Electron Emission Spectra from Foil and Gas Excited Carbon Beams
Auger electron emission spectra from 2 MeV C+ ions excited by collisions with thin carbon foils and Ne gas are presented. The similarity of qualitative features for the C+ → C (foil) and C+ → Ne spectra indicates the similarity of ionization mechanisms for beam foil and beam gas excitation. The spectra were normalized to the lowest lying Li-like quartet state (1s 2s 2p) 4po in carbon by comparison with time delayed foil excited electron decay-in-flight spectra. Comparison to Hartree Fock calculated transition energies indicates that transitions in three and four electron carbon ions dominate the prompt spectra.
