Abstract: | Spectra of saturated absorption of Sm atomic vapor from the ground state 7 F 0 and the first even metastable level 7 F 1, ε′=292.58 cm?1 of the 4f 66s 2 configuration to the odd level 4f 6(7 F)6s6p(3 P o)9 F 1 o , ε,=14863.85 cm?1 were recorded. The lines of the isotopic series were identified, and the hyperfine structure of lines in the spectra of isotopes with a nonzero nuclear spin was determined. The relative isotopic shifts and the hyperfine splitting of the even level 4f 66s 2(7 F 1) were determined. |
