The hyperne structures of four levels of the Sm isotopes have been measured by means of
diode-laser-based Doppler-free saturated absorption spectroscopy in combination with a diodelaser-
initiated resonance-ionization mass spectroscopy. It was demonstrated that combining the
two spectroscopic methods was very eective for the identication and accurate measurement of
the spectral lines of atoms with several isotopes, such as the rare-earth elements. From the obtained
spectra, the hyperne constants A and B for the odd-mass isotopes 147Sm and 149Sm were
determined for four upper levels of the studied transitions.
