From the wavelength dependences of the PID, we suggest that the photoexcitation of the adsorbate (2π. level) is the more important mechanism for Ag and Cu for photon energy≥3.4 eV;

Even though the study of such processes is a new field and the number of experiments is still small compared to that of classical DIET processes [4–6] stimulated by electron bombardment or synchrotron radiat
