A COINCIDENCE COUNTING STUDY OF SPONTANEOUS DESORPTION Academic Article

abstract

• The "spontaneous" emission of ions and photons from surfaces was studied with coincidence counting time-of-flight mass spectrometry. Photons were produced by the spontaneous desorption process with an experimental yield of about 0.01%. Both positive and negative secondary ion yields were measured under various conditions. Results imply classes of desorption events. This may indicate that several types of primary ions are being produced during a single experiment. There was no detectable change in the types of primary ions involved in the spontaneous desorption process as a function of sample potential within the range examined. Positive and negative valine molecular ion yields were found to be similar. 1993.
