Abstract

The hyperfine structure of highly charged lithiumlike ions is considered within QED using the

\frac{1}{Z}

perturbation theory (

Z

is the nuclear charge). The interelectronic interaction contribution of the order of

\frac{1}{Z}

to the hyperfine splitting of the ground state is calculated in the range

Z = 5 - 100

. The hyperfine splitting values are found for the ground state of

{}^{57}{Fe}^{23 +}

and

{}^{209}{Bi}^{80 +}

.
