Vibrationally 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 کاملTime-resolved measurement of interatomic coulombic decay in Ne2.
The lifetime of interatomic Coulombic decay (ICD) [L. S. Cederbaum et al., Phys. Rev. Lett. 79, 4778 (1997)] in Ne2 is determined via an extreme ultraviolet pump-probe experiment at the Free-Electron Laser in Hamburg. The pump pulse creates a 2s inner-shell vacancy in one of the two Ne atoms, whereupon the ionized dimer undergoes ICD resulting in a repulsive Ne+(2p(-1))-Ne+(2p(-1)) state, which...
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 کاملMulti-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 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...
