摘要: Saturation spectroscopy with resonance-ionization mass spectrometry detection was used to obtain Doppler-free spectra of the D23/2°←D23/2 transition lutetium at 22 125 cm−1 in unenriched, naturally occurring samples. Analysis yielded hyperf ine coupling constants 175Lu and 176Lu for this transition. Applications isotopically selective photoionization large-ratio isotopic analysis are discussed.
