High-resolution laser-rf double-resonance spectroscopy has been performed in the 4f/sup 6/ 6s/sup 2/ /sup 7/F/sub 6/ (4020.66 cm/sup -1/), 4f/sup 6/ 5d6s /sup 9/H/sub 2/(11044.90 cm/sup -1/), 4f/sup 6/ 5d6s /sup 9/H/sub 3/ (11406.50 cm/sup -1/), and 4f/sup 6/ 5d6s /sup 7/H/sub 3/ (13542.80 cm/sup -1/) metastable levels of Samarium I. Hyperfine parameters have been deduced with an absolute accuracy of approx. 2 kHz. By means of laser-induced fluorescence, hyperfine constants have been determined in excited levels up to approx. 30560 cm/sup -1/, and isotope shifts measured for 11 lines.
