“…We have carried out so far basic research on laser Gd isotope separation. [1][2][3][4][5][6][7][8][9][10] The absorption spectra of Gd were measured using yellow-red dye lasers with a high resolution, and the isotope shifts and hyperfine structures were analyzed. 1,2,11,12) An absorption spectrum of Gd showed a complex structure because two odd isotopes have hyperfine structures.…”

Laser-induced fluorescence spectroscopy using a single-longitudinal-mode diode laser has been applied to investigating isotope shifts and the hyperfine structures of gadolinium in the wavelength region of 400 nm. Six absorption spectra of transitions from the ground and low-lying metastable levels were measured. The isotope shift per unit mass change varied from 0.6 to 1.0 GHz depending on the transition. The hyperfine splitting constants of 157Gd and 155Gd isotopes were determined for the six upper levels of the transitions. The absorption spectrum of the 999–25661 cm-1 transition showed the narrowest spectral width for odd isotopes.
