The O2 desorption collimated in inclined ways in the plane along the surface trough, confirming the hot-atom collision mechanism. In the presence of CO(a), the product CO2 desorption also collimated in an inclined way, whereas the inclined O2 desorption was suppressed. The inclined O2 and CO2 desorption is explained by a common collision-induced desorption model. At high O2 coverage, the CO2 desorption collimated closely along the (111) terrace normal.American Institute of Physics2005engjournal articleVoRhttp://hdl.handle.net/2115/5512http://www.aip.org/https://doi.org/10.1063/1.2006678161643570021-9606The Journal of Chemical Physics123094702https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5512/1/JCP123-9.pdfapplication/pdf555.9 KB2005
