Hyperfine induced $1s2s ^1S_0 \to 1s^2 ^1S_0$ M1 transition of He-like ions

Jiguang Li, Per Jönsson, Gediminas Gaigalas +1

Hyperfine induced $1s2s ^1S_0 \to 1s^2 ^1S_0$ M1 transition probabilities of He-like ions have been calculated from relativistic configuration interaction wavefunctions including t…
