Cluster KN formation by Rydberg collision complex stabilization during scattering of a K beam off zirconia surfaces

摘要: The molecular beam scattering of a K atom off zirconia surface at 1100 is studied with four different detection techniques: field ionization, which sensitive only to ionizable Rydberg species, in this case, principal quantum number n>29; ion collection, positive ions; multiplier detection, will give response for both ions and species; finally, ionization signal proportional the flux all forms K, including excited K* species clusters KN. Combining these methods, processes can be disentangled. A condensation process observed between an electronically cluster KN* surface. This seen angular distributions as several sharp peaks directions center-of-mass motion complexes formed. Electronically are formed by thermal excitation due mechani...
