Abstract

We identified interatomic Coulombic decay (ICD) channels in argon dimers after spectator-type resonant Auger decay 2p^-1~3d → 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.
