We identified interatomic Coulombic decay ({ICD)} channels in argon dimers after spectator-type resonant Auger decay 2p−13d→3p−23d,4d in one of the atoms, using momentum-resolved electron-ion-ion coincidence. The results illustrate that the resonant core excitation is a very efficient way of producing slow electrons at a specific site, which may cause localized radiation damage. We find also that {ICD} rate for 3p−24d is significantly lower than that for 3p−23d.
