用原子束激光光谱法测量了Sm中4f 65 d 6s组态高位亚稳9 HJ（J= 1-7）态的12个跃迁的同位素位移和超精细结构.对Sm 147和Sm 149的9个H J（J= 1-7）态和6个高能级跃迁，测定了它们的超精细常数A和B. $J-依赖的同位素位移观察到的4f 65 d 6s 9 H项。对4f 65 d 6s组态，导出了交叉二阶效应的参数z5 d，得到z5 d/λ = 165（10）MHz/fm2.结果表明，场位移在交叉二阶效应中占主导地位。
Isotope shifts and hyperfine structures of twelve transitions from the high-lying metastable 9 H J (J= 1–7) states of the 4 f 6 5d6s configuration in Sm i have been measured for the stable isotopes by means of atomic-beam laser spectroscopy. Hyperfine constants A and B for the odd-mass isotopes Sm 147 and Sm 149 are determined for the 9 H J (J= 1–7) states and six upper levels of the transitions in Sm i. $ J—dependences of the isotope shifts are observed for the 4 f 6 5d6s 9 H term. Parameters z 5 d of the crossed-second-order effect are derived for the 4 f 6 5d6s configuration, and z 5 d/λ is found to be 165 (10) MHz/fm 2. It has been verified that the field shift is dominant in the crossed-second-order effect.
