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.

Abstract
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.
