Hyperfine Structure of the Spectrum of Ruthenium Part III

The hyperfine structure of the spectrum of Ru I was studied, and it was found that the ratio of the distances of the components due to the even isotopes is given by Δ(104-102) : Δ(102-100) : Δ(100-96)/2=1 : 1.05±0.10 : 0.75±0.15. There is reason to suppose that the shift Δ(98-96) is anomalously small compared with the shift Δ(104-102) or Δ(102-100). The magnetic moments of the odd isotopes were calculated to be µ(Ru 101 )=-0.69±0.15 nm, and µ(Ru 99 )=-0.63±0.15 nm.
