Vortices associated with the wave function of a single electron emitted in slow ion-atom collisions

Atomic Physics 2014-02-28 v1

Abstract

We present measurements and calculations of the momentum distribution of electrons emitted during the ion-atom collision 10 keV/u He2++HeHe++He2++eHe^{2+}+He \rightarrow He^{+} + He^{2+} + e^{-}, which show rich structures for ion scattering angles above 2 mrad arising dominantly from two-electron states. Our calculations reveal that minima in the measured distributions are zeros in the electronic probability density resulting from vortices in the electronic current.
