Abstract

High-resolution laser-rf double-resonance spectroscopy has been performed in the

4 f^{6} 6 s^{2} {}^{7}F_{6}

(4020.66

{cm}^{- 1}

4 f^{6} 5 d 6 s {}^{9}H_{2}

(11044.90

{cm}^{- 1}

4 f^{6} 5 d 6 s {}^{9}H_{3}

(11406.50

{cm}^{- 1}

), and

4 f^{6} 5 d 6 s {}^{7}H_{3}

(13542.80

{cm}^{- 1}

) metastable levels of Samarium i. Hyperfine parameters have been deduced with an absolute accuracy of ∼ 2 kHz. By means of laser-induced fluorescence, hyperfine constants have been determined in excited levels up to ∼ 30560

{cm}^{- 1}

, and isotope shifts measured for 11 lines.
