Observation of interatomic Coulombic decay in Ne dimer above and below the Ne 2 s - 1 threshold

Introduction It is well now that, in rare gas atoms, inner-shell core holes usually decay by emitting a secondary Auger electron. This pathway is forbidden in case of inner valence holes, for their binding energy lies below the lowest double ionization potential. Consequently, they can only experience a radiative decay. However, when the rare gas atom is a part of a weakly bound van der Waals c...

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...

Interatomic Coulombic decay cascades in multiply excited neon clusters

In high-intensity laser light, matter can be ionized by direct multiphoton absorption even at photon energies below the ionization threshold. However on tuning the laser to the lowest resonant transition, the system becomes multiply excited, and more efficient, indirect ionization pathways become operative. These mechanisms are known as interatomic Coulombic decay (ICD), where one of the specie...

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...
