摘要：

In this paper a UHV apparatus for studying adsorption of gases on surfaces will be described. The system is specifically designed for measuring the sticking coefficient of a molecule on the surface and its dependence on energy and angle of incidence. The method is based on the use of an electron energy loss spectrometer which detects the amount of the adsorbed species as a function of the exposure of the surface to a supersonic nozzle beam which deposits the molecular species at different energies and angles of incidence. Measurements of the sticking probability of O2 on Ag(001) are presented showing the capability of the method.
