AUGER ELECTRON SPECTROSCOPY OF CRYOGENIC MATRIX ISOLATED METAL ATOMS AND DIRECT RECOIL SPECTROSCOPY (DRS), SIMS AND XPS STUDIES ON TITANIUM AND PIQ
Auger electron spectra of matrix-isolated metal atoms have been recorded for the first time. Differences in extra-atomic relaxation between bulk metal and argon matrix isolated atoms resulted in shifts in the energy of LMM Auger electrons, $-3.1$ eV for potassium and $-8.7$ eV for titanium. The sum …
