Interatomic or intermolecular Coulombic decay (ICD) is a nonlocal electronic decay
mechanism occurring in weakly bound matter. In an ICD process, energy released by …

Molecules involved in solvation shells have properties differing from those of the bulk
solvent, which can in turn affect reactivity. Among key properties of these molecules are their …

We report on the experimental observation of the direct decay of a core vacancy in van der
Waals clusters by emission of a fast electron from a neighboring atom. The process can be …

Photoionization of a weakly bound van-der-Waals dimer, composed of two atomic species A
and B, is studied theoretically. Atom A can be ionized either directly or via an indirect two …

Electron-impact ionization of an atom or ion in the presence of a neighboring atom is
studied. The latter is first collisionally excited by the incident electron, whose energy is …

A free electron can form a bound state with an atomic center A upon photoemission
(radiative recombination). In the presence of a neighboring atom B, such a bound state can …

We study single ionization of a heteroatomic system by charged projectiles whose velocity v
approaches the speed of light c. The system is formed by two loosely bound atomic species …

The double ionization of an atom by single-photon absorption in the presence of a
neighbouring atom is studied. The latter is, first, resonantly photoexcited and, afterwards …

Ionization-excitation of an atom induced by the absorption of a single photon in the presence
of a neighboring atom is studied. The latter is, first, resonantly photoexcited and, afterwards …

We explore a mechanism for ionization in high-velocity (but not yet relativistic) collisions of
light atomic particles, one of which being initially in an excited internal state. This …
