Multi-coincidence spectroscopy on interatomic Coulombic decay
The inner-shell ionized states in matter are subject to Auger decay. Auger spectra are considered as fingerprint images of the atom where the inner-shell hole is created. About a decade ago, Cederbaum and coworkers [1] proposed a new mechanism of electronic decay where the environment plays a role. For an isolated atom or molecule with an innervalence vacancy, Auger decay is often energetically...
متن کاملInteratomic Coulombic decay in mixed NeKr clusters.
We report the occurrence of interatomic Coulombic decay (ICD) in mixed NeKr clusters. A well-defined feature ranging from 9 to 12 eV in kinetic energy is observed in coincidence with the Ne 2s photoelectrons. It derives from an ICD process, in which an initial Ne 2s vacancy is filled by a Ne 2p electron and an electron is emitted from a 4p level on a neighboring Kr atom. We have studied the dep...
متن کاملVibrationally resolved decay width of interatomic Coulombic decay in HeNe.
We investigate the ionization of HeNe from below the He 1s3p excitation to the He ionization threshold. We observe HeNe+ ions with an enhancement by more than a factor of 60 when the He side couples resonantly to the radiation field. These ions are an experimental proof of a two-center resonant photoionization mechanism predicted by Najjari et al. [Phys. Rev. Lett. 105, 153002 (2010)]. Furtherm...
متن کاملExperimental evidence for interatomic coulombic decay in Ne clusters.
Electron spectra of photoexcited Ne clusters are shown to display a signal at low kinetic energies that is neither present in the Ne monomer nor at photon energies below the inner-valence 2s threshold. These findings are strong evidence for the existence of interatomic Coulombic decays (ICD), a mechanism that was recently predicted theoretically [Phys. Rev. Lett. 79, 4778 (1997)]]. In ICD, an i...
متن کاملExperimental observation of interatomic coulombic decay in neon dimers.
Recently Cederbaum et al. [Phys. Rev. Lett. 79, 4778 (1997)]] predicted a new decay channel of excited atoms and molecules termed interatomic Coulombic decay (ICD). In ICD the deexcitation energy is transferred via virtual photon exchange to a neighboring atom, which releases it by electron emission. We report on an experimental observation of ICD in 2s ionized neon dimers. The process is unamb...
