Application of resonance ionization mass spectrometry to the lanthanide elements in the wavelength region of 430-455 nm

A study of all the lanthanides except promethium has been carried out using resonance ionization mass spectrometry; the wavelength region for this investigation was 430-450 nm. A list of several wavelengths is given for each of these lanthanides where they can be determined without isobaric interference of other lanthanides. The optical routes for ionization were cataloged in terms of 1 + 1, 1 + 1 + 1, and 2 + 1 photon pathways where possible, and the known or partially known routes are presented. Possible pathways for the unknown optical routes are evaluated. (author)
