New Nuclear Magnetic Moment of $^{209}$ Bi - Resolving the Bismuth Hyperfine Puzzle

Leonid V. Skripnikov, Stefan Schmidt, Johannes Ullmann +9

A recent measurement of the hyperfine splitting in the ground state of Li-like $^{209}$ Bi $^{80 +}$ has established a "hyperfine puzzle" -- the experimental result exhibits a 7 $σ$ de…
