The intensity of light emission from excited Al atoms sputtered from a metal surface strongly depends on the degree of oxygen coverage θ of the target surface. Desorption cross section of an adsorbed oxygen atom by Ar^+ bombardment was obtained for a polycrystalline Al surface by means of a time transient spectroscopic technique. The results obtained is (3.7 ±0.2) × 10^-16cm^2 for the Al polycrystalline target at the projectile energy of 40 keV. The initial sticking probability so of an adsorbing oxygen atom was estimated and the value obtained agreed to the reported values within experimental errors. A very sharp spike in intensity was found to appear for the resonance line of Al atom sputtered from the Al surface in a transient experiment when the oxygen coverage becomes large (θ〜1) in addition to a decay curve usually observed with a large time constant.
