A spectral study of promethium and samarium in the wavelength ranges of 530 to 560 and 580 to 615 nm has been made by resonance ionization mass spectrometry. A total of 54 promethium and 35 samarium ionization wavelengths were found. These optical routes are thought to involve a single-color, three-photon process. On the basis of this premise, new qualitative spectral information for both these elements is obtained from these data, and directions for more definitive studies result.
