New radiative lifetime measurements performed with time-resolved laser spectroscopy for the 6p1/2 and 6p3/2 levels of La III provide a unique opportunity for testing the adequacy of the relativistic Hartree-Fock approach for atomic structure calculations in this ion. As a consequence of the comparison, an extensive set of accurate f-values is provided for many La III and Lu III UV and visible transitions of astrophysical interest.
