Abstract

Figure 2.1 illustrates the schematic experimental arrangement for photoelectron spectroscopy. It consists of a light source, an interaction region where the photon beam collides with the gas under consideration, an electron spectrometer, and an electron detector. In conventional PES, one uses sources emitting light of a fixed wavelength (mostly 584 Å ≙ 21.22 eV produced in a He discharge lamp). The target gas is introduced in the reaction volume simply by effusing from a capillary. By scanning the electron energy analyzer, electrons of only one energy at a certain time are transmitted to the detector. By synchronizing the electron energy analyzer with a multichannel analyzer (MCA) a given channel (position on the X axis) is made to correspond to a particular electron energy, yielding a differential photoelectron spectrum, as indicated in Fig. 2.1.
