Isotopically Selective, Doppler-Free, Saturation Spectroscopy of Lutetium Isotopes Via Resonance Ionization Mass Spectrometry

摘要

A new technique utilizing RIMS to obtain very high resolution atomic spectra with isotopic selectivity has been demonstrated. This technique allows the precise determination of HF splitting constants, limited only by the transition's natural linewidth. In addition, it is also feasible with this technique to accurately determine atomic isotope shifts. The exact determination of HF component line positions provides data for isotopically selective ionization which, in turn, will increase RIMS' dynamic range. Future work includes the incorporation of a /open quotes/vibrating/close quotes/ mirror and the study of rarer isotopes, i.e., sup 174 Lu, sup 173 Lu, sup 172 Lu, sup 171 Lu, and possibly, sup 170 Lu. 13 refs., 3 figs.
