fragments are recorded in coincidence with C(1s) KVV Auger electrons for 3 different photon energies and both vertical and horizontal polarization of the incident radiation. The angular distribution of the Auger electrons is found to be independent of both energy and polarization, and the two-step model deemed to be valid.

Times Cited Count：23 Percentile：72.33(Spectroscopy)Interatomic Coulombic decay (ICD) in Ar
, ArKr and Kr following Ar 2p or Kr 3d Auger decay has been investigated by means of momentum-resolved electron-ion-ion-coincidence spectroscopy. This sequential decay leads to Coulombic dissociation into dication and monocation. Simultaneously determining the kinetic energy of the ICD electron and the kinetic energy release between the two atomic ions, we could unambiguously identify the ICD channels. We find that, in general, spin conserved ICD, in which the singlet (triplet) dicationic state produced via the atomic Auger decay preferentially decays to the singlet (triplet) state, transferring the energy to the other atom, is faster than the spin-flip ICD, in which the Auger final singlet (triplet) dicationic state decays to the triplet (singlet) state.
