Ion impact induced Interatomic Coulombic Decay in neon and argon dimers

Abstract

We investigate the contribution of Interatomic Coulombic Decay induced by ion impact in neon and argon dimers (Ne${}_2$ and Ar${}_2$) to the production of low energy electrons. Our experiments cover a broad range of perturbation strengths and reaction channels. We use 11.37 MeV/u S${}^{14+}$, 0.125 MeV/u He${}^{1+}$, 0.1625 MeV/u He${}^{1+}$ and 0.150 MeV/u He${}^{2+}$ as projectiles and study ionization, single and double electron transfer to the projectile as well as projectile electron loss processes. The application of a COLTRIMS reaction microscope enables us to retrieve the three-dimensional momentum vectors of the ion pairs of the fragmenting dimer into Ne${}^{q+}$/Ne${}^{1+}$ and Ar${}^{q+}$/Ar${}^{1+}$ (q = 1, 2, 3) in coincidence with at least one emitted electron.
