Research conducted in the Ames Laboratory Nuclear Safeguards and Security Program during the period October 1, 1991 to December 31, 1991 is reviewed. Current work in applying optical spectroscopy to the determination of actinide and related elements in the gas phase is discussed. The major portion of this report is devoted to a description of a successful modification to a high-temperature heat pipe oven described in a previous report. High-resolution spectra of rare earth elements volatilized in this oven, measured using Doppler-free spectroscopy (i.e., saturated absorption spectroscopy) are presented along with a comparison of the spectrum of samarium measured with Doppler-free and ordinary techniques. Rare earth elements have strong spectral similarities to the actinide elements and it is clear from work that Doppler-free methods applied to the actinides will be very selective and capable of isotopic resolution.
