Measurement of the isolated nuclear two-photon decay in 72Ge

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 c...
