g-factor of a tightly bound electron

Abstract

We study the hyperfine splitting of an electron in hydrogen-like ${}^{209}B{i}^{82+}$. 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.
