Electron localization in dissociating $H_2^+$ by retroaction of a photoelectron onto its source
Abstract
We investigate the dissociation of into a proton and a after single ionization with photons of an energy close to the threshold. We find that the and the do not emerge symmetrically in case of the dissociating along the ground state. Instead, a preference for the ejection of the in the direction of the escaping photoelectron can be observed. This symmetry breaking is strongest for very small electron energies. Our experiment is consistent with a recent prediction by Serov and Kheifets [Phys. Rev. A 89, 031402 (2014)]. In their model, which treats the photoelectron classically, the symmetry breaking is induced by the retroaction of the long range Coulomb potential onto the dissociating .
