Abstract :
Sub-Doppler spectra of La I were measured for some transition lines by the polarization intermodulated excitation method (POLINEX) and the saturation absorption (SAS) spectroscopy method. From the obtained spectra, we determined the hyperfine structure of the upper level of /sup 139/La isotope and hyperfine constants A and B.
