Not every interaction between a photon and an atom, or molecule, will result in photoionization. The probability of photoionization is related to the photoionization cross section of the species -- the probability of an ionization event conceptualized as a hypothetical cross-sectional area. This cross section … Meer weergeven Photoionization is the physical process in which an ion is formed from the interaction of a photon with an atom or molecule. Meer weergeven Several photons of energy below the ionization threshold may actually combine their energies to ionize an atom.
