Sequential interatomic decay, where the first step is an Auger decay with interatomic character and the second step is a pure interatomic Coulombic decay (ICD), is identified in Ar trimers Ar3. The 2p hole state in Ar 3 decays via the L2,3M1M2,3 Auger to the one-site two-hole states Ar++(3s-13p -1)-Ar-Ar that couples to the two-site satellite states Ar +(3p-2nℓ)-Ar+(3p-1)-Ar. These states are subject to ICD to the states Ar+(3p-1)-Ar +(3p-1)-Ar+(3p-1), in which the nℓ electron fills the 3p hole in the same Ar site and one of the 3p electrons in the third Ar site is emitted as a slow ICD electron. This ICD process is identified unambiguously by electron-ion-ion-ion coincidence spectroscopy in which the kinetic energy of the slow ICD electron and the kinetic energy release among the three Ar+ ions are measured in coincidence.
