      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.},
