Abstract
Angular distributions of neutral CO desorbed by electron impact from chemisorbed CO on Ru(001), and of neutral N2O and N2 from chemisorbed and physisorbed N2O on Ru(001), have been measured and compared to angular distributions of desorbing ions. All distributions are peaked around the surface normal. Angular widths of neutrals are generally broader than those of ions, but are much narrower than for thermal desorption, and show large differences. The results are discussed in terms of mechanisms of ionic and neutral desorption.
