摘要：

The chemisorption dynaMiCS Of O2 and Ag(110) was studied by molecular beams and high resolution electron energy loss spectroscopy by measuring the initial sticking probability S0 as a function of the molecular translational energy E(i) and angle of incidence theta(i) along [001] and [110BAR]. S0 scales as E(i)cos(n)theta(i) with n = 1.1 along (001) and n = 1.6 along [110BAR]. This indicates that parallel momentum has a role in promoting adsorption. The effect is connected to the amplitude of the corrugation seen by the O2 molecule.
