Multiple‐coincidence techniques involving detection of two near‐threshold electrons in coincidence with each other and with product ions are proposed to measure spectra of doubly charged ions and the decay of their energy‐selected states. The new techniques are demonstrated by laboratory experiments on double photoionization of CO 2 and SO 2 .
