Abstract

The transition probabilities of the lines ¹S₀–³P₀ and ¹S₀–³P₂ of the s²–sp arrays in Mg i, Zn i, Cd i, and Hg i, which arise by the interactions of the nuclear moments with the electrons, are computed for each odd isotope individually and for the naturally occurring isotopic mixture. The individual hyperfine structure component transition probabilities are given for the ¹S₀–³P₂ lines. Part of the intensity of the lines arises from the interaction of ³P₀ or ³P₂ with ³P₁ and part from the interaction of ³P₀ or ³P₂ with ¹P₁, the former being more important for ¹S₀–³P₀ and the latter for ¹S₀–³P₂. Spin-spin and spin-other-orbit interactions in Mg i are calculated for the 3s3p³P term and compared with observations.
