Abstract:
Photoemission induced by vacuum ultraviolet resonance radiation of xenon atoms from the surface of a solid in vacuum and in the case of a target in contact with a gas has been experimentally studied. It has been demonstrated that the photoemission response increases strongly (up to an order of magnitude) under the adsorption (or implantation) of gas atoms into the target when vacuum ultraviolet radiation resonantly acts on these atoms. This is due to different mechanisms of photoemission from the surface of the solid in vacuum and from the surface in contact with the gas. The notion of activated resonant photoemission has been introduced.
