Ionized photon
Did you know?
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. This probability decreases rapidly with the number of … Meer weergeven • Ion source • Radiolysis Meer weergeven When either the laser intensity is further increased or a longer wavelength is applied as compared with the regime in which multi-photon ionization takes place, a quasi … Meer weergeven • Uwe Becker; David Allen Shirley (1 January 1996).
