Efficient site-specific low-energy electron production via interatomic Coulombic decay following resonant Auger decay in argon dimers

摘要

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