The nuclear two-photon or double-gamma ( $2 γ$ ) decay is a second-order electromagnetic process whereby a nucleus in an excited state emits two gamma rays simultaneously. To be able to directly measure the $2 γ$ decay rate in the low-energy regime below the electron-positron pair-creation threshold, we combined the isochronous mode of a storage ring with Schottky resonant cavities. The newly developed technique can be applied to isomers with excitation energies down to $\sim 100 keV$ and half-lives as short as $\sim 10 ms$ . The half-life for the $2 γ$ decay of the first-excited $0^{+}$ state in bare ${}^{72}{Ge}$ ions was determined to be 23.9(6) ms, which strongly deviates from expectations.
