AES, LEED, ELS and work function determination were used in order to study H//2 and C//2H//4 adsorption on Al(100). Results indicate that C//2H//4 and H//2 adsorb dissociatively at room temperature. The adsorbed species are incorporated into ordered islands at intermediate exposures. At high exposures the adsorbed species are probably deposited on the surface. Present results indicate that incorporation is randomlike for C//2H//4 adsorption at minus 80 degree C. Conversion to an ordered structure results from heating at minus 30 degree C. At high current density electron beam stimulates hydrocarbon desorption upon C//2H//4 adsorption and leads to a random incorporation of hydrogen, probably in the form of an amorphous hydride.
