Abstract

We have identified interatomic Coulombic decay (ICD) processes in the ArKr dimer following Ar 2p Auger decay, using momentum-resolved electron-ion-ion coincidence spectroscopy and simultaneously determining the kinetic energy of the ICD electron and the KER between Ar2+ and Kr+. We find that the spin-conserved ICD processes in which Ar2+(3p -33d) 1P and 3P decay to Ar 2+(3p-2)1D and 3P, respectively, ionizing the Kr atom, are significantly stronger than the spin-flip ICD processes in which Ar2+(3p-33d) 1P and 3P decay to Ar2+(3p-2)3P and 1D, respectively.
