| Abstract: | The formation of singly and doubly charged ions upon nonlinear ionization of barium atoms is studied as a function of the frequency and intensity of a 8800-8920-cm?1 IR color center laser. Barium atoms are ionized via the four-photon resonance with the strongly perturbed bound 6p 2 1 D 2 state. Doubly charged barium ions are produced by a two-electron mechanism. It is found that the probability of the formation of doubly charged ions under these conditions linearly depends on the laser radiation intensity. |
