Abstract
We said in Chap. 1 that in nonlinear ionization of atoms (i.e., when the photon energy ω is less than the atomic ionization potential E i ) the energy of K photons (where K 1 < K the threshold number of photons required for atomic ionization) may be equal to the transition energy between the initial (for example, the ground state) state i to some excited bound state k. We assume that the multiphoton limit is attained (the adiabaticity parameter ≫ 1) and that the considered atomic transition is allowed by selection rules. Ionization in the presence of such an intermediate resonance is called resonance-enhanced ionization.
