Resonance three-photon ionization of samarium atom by laser radiation in the range from 17200 to 17900 cm−1
Aleksandr I. Gomonai, О. И. Куделич
For the first time, three-photon ionization of a samarium atom in the spectral range between 17200 and 17900 cm −1 was studied. More than 300 peaks with different amplitudes and shape are revealed in the spectral efficiency of the Sm + ion formation. The majority of peaks observed is attributed to two-photon excitation of the bound even-parity states in the energy range above 35780 cm −1 . The energies and the total momenta of the states are determined.
