Thin condensed films of rare-gas atoms (Ar, Kr, Xe), grown on a Pt(111) crystal, have been exposed to monochromatic low-energy electrons (E = 5 –; 25 eV, ΔE = 60 meV). Desorbed metastable atoms are abundant for Ar films, and several desorption components are identified based on the information on flight time and desorption angle. With Kr and Xe, a significant metastable atom signal is obtained only by covering a Kr film with a monolayer of Xe. Various desorption mechanisms are discussed.
