Longstanding problems in the comparison of very accurate hyperfine-shiftmeasurements to theory were partly overcome by precise measurements onfew-electron highly-charged ions. Still the agreement between theory andexperiment is unsatisfactory. In this paper, we present a radically new way ofprecisely measuring hyperfine shifts, and demonstrate its effectiveness in thecase of the hyperfine shift of $4s\_{1/2}$ and $4p\_{1/2}$ in$^{207}\mathrm{Pb}^{53+}$. It is based on the precise detection of dielectronicresonances that occur in electron-ion recombination at very low energy. Thisallows us to determine the hyperfine constant to around 0.6 meV accuracy whichis on the order of 10%
