Abstract: | Very high efficiency of Raman scattering on samarium atoms in the process of three-photon ionization has been detected. An intense maximum attributed to the one-photon transition 4f 65d6s 9 H 2 → 4f 55d6s 2 7 D 3° between two excited states is observed in the dependence of the yield of Sm+ ions on the laser-radiation frequency. The 4f 65d6s 9 H 2 state is populated owing to the spontaneous Raman scattering 4f 66s 2 7 F 3 + ω ? ν → 4f 65d6s 9 H 2. |
