We present the electron spectra for 07+ on a polycrystalline tungsten surface at collision energies between 100 eV and 100 keV. We find clearly resolved structures from projectile KLL-and LMM Auger electrons. The relative intensities of these peaks show that the n=2 level is partly populated by ‘side-feeding’ processes. The time dependence of the KLL peak and the LMM peak can be described by a single exponential.
