摘要：

Laser spectroscopy of a thermal atomic beam of natural lanthanum has been performed. An active filtering technique has been used to remove spurious cavity modes from the laser output, leading to unambiguous identification of hyperfine structure associated with La-138. Hyperfine structure coefficients and isotope shifts for several transitions of the isotopes La-138 and La-139 are presented.
