gfactor of a tightly bound electron

Abstract

We study the hyperfine splitting of an electron in hydrogen-like 209 Bi 82+ . It is found that the hfs energy splitting can be explained well by considering the g-factor reduction due to the binding effect of a bound electron. We determine for the first time the experimental value of the magnetic moment of a tightly bound electron.

Hyperfine anomaly of Be isotopes and anomalous large anomaly in11Be

“…Recently, much interest has been paid to the magnetic hyperfine structure (hfs) for various nuclear isotopes [1,2,3,4,5,6]. For the experimental side, there is some progress in observing the transition of the hyperfine levels for atomic ground states.…”
