Surface ionization of atomic beams of strontium or calcium from the [110] and the [111] directions of tungsten was studied mass-spectrometrically. Results consistent with the Saha-Langmuir relation indicate that the method is applicable for the determination of first ionization potentials or work functions. A value for the work function of the STA110! direction is 5.41 plus or minus 0.04 ev. A value for the work function of the [110] direction of tungsten is 4.49 plus or minus 0.04 ev.
