Electron localization in dissociating $H_{2}^{+}$ by retroaction of a photoelectron onto its source

M. Waitz, D. AslitÃ¼rk, N. Wechselberger +19

We investigate the dissociation of $H_{2}^{+}$ into a proton and a $H^{0}$ after single ionization with photons of an energy close to the threshold. We find that the $p^{+}$ and the $H^{0}$ …

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

L. Ph. H. Schmidt, C. Goihl, D. Metz +5

We present measurements and calculations of the momentum distribution of electrons emitted during the ion-atom collision 10 keV/u $H e^{2 +} + H e \to H e^{+} + H e^{2 +} + e^{-}$ ,…

Vibrationally Resolved Decay Width of Interatomic Coulombic Decay in HeNe

F. Trinter, J. B. Williams, M. Weller +17

We investigate the ionization of HeNe from below the He 1s3p excitation to the He ionization threshold. We observe HeNe $^{+}$ ions with an enhancement by more than a factor of 60 whe…

Quasi-molecular electron promotion beyond the 1s $I ¨ $ and 2p $I ¨ $ channels in slow collisions of He $^{2 +}$ and He

L. Ph. H. Schmidt, M. S. SchÃ¶ffler, C. Goihl +3

The electron emission pattern of transfer-ionization in collisions of He $^{2 +}$ with He was investigated for impact velocities between 0.53 a.u. and 0.77 a.u. (7 keV/u - 15 keV/u)…

Imaging the He $_{2}$ quantum halo state using a free electron laser

S. Zeller, M. Kunitski, J. Voigtsberger +24

We report on coulomb explosion imaging of the wavefunction of the quantum halo system He $_{2}$ . Each atom of this system is ionized by tunnelionization in a femto second laser pulse…

A measurement of the evolution of Interatomic Coulombic Decay in the time domain

F. Trinter, J. B. Williams, M. Weller +17

During the last 15 years a novel decay mechanism of excited atoms has been discovered and investigated. This so called ''Interatomic Coulombic Decay'' (ICD) involves the chemical e…

Interatomic-Coulombic-decay-induced recapture of photoelectrons in helium dimers

P. Burzynski, F. Trinter, J. B. Williams +17

We investigate the onset of photoionization shakeup induced interatomic Coulombic decay (ICD) in He2 at the He+*(n = 2) threshold by detecting two He+ ions in coincidence. We find…
