  5. In fact, for incident radiation at 6328 Å, the single quantum contribution to the photocurrent from the Fermi tail was so large that it precluded observation of a double-quantum current. In this case, the current from the photocathode was measured directly.
  6. If a volume effect is responsible for the transitions, however, then for film thicknesses below a critical thickness dcrit, α depends on the thickness of the film [see H. Thomas, Z. Physik 147, 395 (1957)]. That is, below dcrit (which is the depth of photoemission), α will increase approximately linearly with film thickness, corresponding to the amount of sample emitting. This effect is neglected.
