Hydrogen-adsorbed Al(111) single crystal surface was studied by thermal desorption (TD) technique under ultrahigh vacuum. The mass spectra of the desorbing species showed signals corresponding to Al{sup +}, AlH{sup +}, AlH{sub 2}{sup +}, AlH{sub 3}{sup +}, AlH{sub 4}{sup +}, and Al{sub 2}H{sub 6}{sup +}. Hydrogen atoms adsorbed at 150 K on the surface desorbed at 340 K as aluminum hydride.
