“…The assignment of these processes is in line with the findings reported in [75], where the same excited initial state was created by Auger decay or direct triple ionization using a synchrotron photon source. By measuring the KER after Coulomb explosion various decay mechanisms involving rich nuclear dynamics were found for Ar 3 [74]. Particularly, the pathway of the breakup of Ar + 3 4 and Ar + 3 5 is disentangled by comparison to previous work employing photons [38].…”

In pioneering work by Cederbaum et al an excitation mechanism was proposed that occurs only in loosely bound matter (Cederbaum et al 1997 Phys. Rev. Lett. 79 4778): it turned out, that (in particular) in cases where a local Auger decay is energetically forbidden, an excited atom or molecule is able to decay in a scheme which was termed 'interatomic Coulombic decay' (or 'intermolecular Coulombic decay') (ICD). As ICD occurs, the excitation energy is released by transferring it to an atomic or molecular neighbor of the initially excited particle. As a consequence the neighboring atom or molecule is ionized as it receives the energy. A few years later the existence of ICD was confirmed experimentally (

“…Surprisingly, only little work can be found in literature on ICD after electron impact ionization, so far. Very recently Yan et al reported on a corresponding observation [73,74]. A pulsed high energy electron beam ( = E 3 keV) was used to create multiply charged Ar dimers [73] and trimers [74].…”

Interatomic and Intermolecular Coulombic Decay

et al. 2020

Interatomic or intermolecular Coulombic decay (ICD) is a nonlocal electronic decay mechanism occurring in weakly bound matter. In an ICD process, energy released by electronic relaxation of an excited atom or molecule leads to ionization of a neighboring one via Coulombic electron interactions. ICD has been predicted theoretically in the mid nineties of the last century, and its existence has been confirmed experimentally approximately ten years later. Since then, a number of fundamental and applied aspects have been studied in this quickly growing field of research. This review provides an introduction to ICD and draws the connection to related energy transfer and ionization processes. The theoretical approaches for the description of ICD as well as the experimental techniques developed and employed for its investigation are described. The existing body of literature on experimental and theoretical studies of ICD processes in different atomic and molecular systems is reviewed.

“…The experiment was carried out using the Reaction Microscope mounted at the 320-kV platform for multidisciplinary research with highly charged ions at the Institute of Modern Physics, CAS [22][23][24]. Briefly, after being extracted from the electron cyclotron resonance ion source (ECR), the Ne 8+ ions were extracted and accelerated to 50 keV/u when they were leaving the high voltage platform.…”

The fragmentation experiment on doubly and triply ionized Ar dimers is carried out using 1.0 MeV Ne 8+ impact, focusing on the angular distribution of Ar + and Ar 2+ ions. For the fragmentation of (Ar 2 ) 2+ , one-site double ionization and two-site double ionization are distinguished clearly, and different angular distributions are observed for these two channels. This phenomenon is explained qualitatively in simple geometrical considerations. For the fragmentation of (Ar 2 ) 3+ , we find that the Ar + ions tend to fly along the projectile direction, while the doubly charged Ar 2+ ions tend to fly in the opposite direction. This result suggests that, to form the parent ion (Ar 2 ) 3+ , transfer ionization is favorable in the first collision step, while single ionization is dominant in the second collision step.
