The tungsten Lα1,2 x-ray spectrum was measured with high resolution using photoexcitation by monochromatized synchrotron radiation. The line splitting, widths, and relative intensities were determined from a phenomenological fit by five Voigt functions and compared with previous measurements. A fully split diagram and 5l-1 spectator hole transition multiplets were calculated ab initio using the relativistic multiconfigurational Dirac-Fock method. Fits of various combinations of these multiplets to the measured spectrum show that the line shapes can be well accounted for by the fully split diagram transition 2p3/2-1→3d3/2,5/2-1 alone, without invoking contributions from any spectator hole transition.
