Observation of Hyperfine Mixing in Measurements of a Magnetic OctupoleDecay in Isotopically Pure Nickel-LikeXe129andXe132Ions

“…Hyperfine mixing affects the line intensities in atomic and singly ionized heavy elements [1,2] seen in astrophysics [3,4], as well as of susceptible light ions observed in planetary nebulae [5]. The hyperfine levels of the ground state of atomic hydrogen give rise to the 21-cm line used in radioastronomy to image our galaxy and were the basis for the first maser (see [6]).…”
