Single-photon Photoionization Mode (SP)
The SP mode is obtained at small wavelengths (UV, X-ray), or high energy per photon,and at low intensity levels. The only photoionization process involved in this case is the single-photon ionization.

Famous quotes containing the word mode:
“If Thought is capable of being classed with Electricity, or Will with chemical affinity, as a mode of motion, it seems necessary to fall at once under the second law of thermodynamics as one of the energies which most easily degrades itself, and, if not carefully guarded, returns bodily to the cheaper form called Heat. Of all possible theories, this is likely to prove the most fatal to Professors of History.”
—Henry Brooks Adams (1838–1918)
