摘要：

The hyperfine structure of157Gd was investigated in 20 Gd II lines by means of a photoelectric recording Fabry-Perot interferometer with digital data processing. The hyperfine splitting factors, A and B, were obtained by computer fits to the observed line structures. Using a multiconfigurational set of wave functions in intermediate coupling derived by Wyart, mono-electronic hyperfine parameters were deduced by a parametric treatment. The nuclear electric quadrupole moment of157Gd was evaluated from the quadrupole interaction of the 5 d electron in 4 f7 5 d6 s, the 5 d electron in 4 f7 5 d6 p, and the 6 p electron in 4 f7 5 d6 p. The three values obtained for the quadrupole moment agree very well. The final result, corrected for Sternheimer shielding, is Q(157Gd) =1.34(7)·10-24 cm2. © 1979 Springer-Verlag.
