Abstract
A hyperfine state selective laser probing technique is presented to be used for lifetime determination of metastable states in an ion storage ring. Evidence for a drastic difference between the decay rates of the hyperfine states of the metastable level $5d{}^{4}{D}_{7/2}$ in ${}^{129}{\mathrm{Xe}}^{+}$ has been obtained by this method.
