Isotopic shifts and the hyperfine structure of the samarium spectral lines at 672 and 686 nm Academic Article uri icon


  • Spectra of saturated absorption of Sm atomic vapor from the ground state 7F0 and the first even metastable level 7F 1, ε′ = 292.58 cm-1 of the 4f 66s2 configuration to the odd level 4f6( 7F)6s6p(3Po)9F1o, 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 66s2(7F1) were determined. © 2007 MAIK "Nauka/Interperiodica".
