Abstract:

Secondary atomic and molecular ion energy spectra have been obtained for several rare earth and rare earth oxide samples. The energy dependencies of the diatomic ions were found to be a product of the energy dependencies of the atomic ions. Qualitative agreement of this product rule is also found for larger clusters. A recombination mechanism for molecular formation is demonstrated to be consistent with these results. Several preliminary ion implant studies are presented to give further insight into the recombination model. Author
