We report the first observation of hyperfine structures (HFSs) and isotope shifts-(ISs) of Sm I in the range of 540-560 nm using an atomic beam resonance-fluorescence technique. The least square fitting was used to determine hyperfine constants in 4f55d6s2 and 4f66s6p of atomic samarium (Sm I). The isotope shifts of 18 transition lines were also determined and analyzed by the King plot.
