Abstract: The LIBELLE experiment performed at the experimental storage ring at the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, Germany, has successfully determined the ground state hyperfine (HFS) splittings in hydrogen-like (${}^{209}{\mathrm{Bi}}^{82+}$) and lithium-like (${}^{209}{\mathrm{Bi}}^{80+}$) bismuth. The study of HFS transitions in highly charged ions enables precision tests of QED in extreme electric and magnetic fields otherwise not attainable in laboratory experiments. Besides the transition wavelengths the time-resolved detection of fluorescence photons following the excitation of the ions by a pulsed laser system also allows the extraction of lifetimes of the upper HFS levels and g-factors of the bound 1s and 2s electrons for both charge states. While the lifetime of the upper HFS state in ${}^{209}{\mathrm{Bi}}^{82+}$ has already been measured in earlier experiments, an experimental value for lifetime of this state in ${}^{209}{\mathrm{Bi}}^{80+}$ is reported for the first time in this work.
