Isotope shifts and hyperfine structures of four transitions in W i have been measured as well as isotope shifts in Lu i by means of atomic-beam laser spectroscopy. Magnetic-dipole hyperfine constants A of W183 are determined for the atomic states 7D1, 7F1, and 7F3 of the 5d46s6p configuration. The nuclear parameters λ and δ r2 are derived for W stable isotopes. J dependences of the isotope shifts are observed for the 2D term of the 5d6s2 configuration in Lu i and the 5D term of the 5d46s2 configuration in W i. Parameters z5d of the crossed-second-order effects are derived for the Lu i 5d6s2 and W i 5d46s2 configurations, and z5d/λ is found to be 411(26) MHz/fm2 for W. A systematic behavior of the normalized parameter znl/λζnl is discussed.
