Abstract

Isotope shifts are here reported for all stable isotopes of hafnium. The ratios found are: Δσ(180–178):Δσ(178–176):Δσ(176–174)=100:82.6±3.5:87.6±3.7 and Δσ(180–178):Δσ(180–179):Δσ(178–177)=100:61±9:73±8. The variation of the shifts with neutron number and the even-odd staggering are well beyond experimental error, and are therefore real. Magnitudes of the shifts observed in the spectral lines ranged from 29 to 46 mK. Centroids of the hyperfine-structure patterns due to the odd isotopes were located by using known ratios of the nuclear moments or of the hyperfine-structure parameters. The difference in the electric quadrupole moments between isotopes are discussed from the point of view of isotope-shift anomalies.
