Ejection of quasi-free electron pairs from the helium atom ground state by single photon absorption
M. S. Schöffler, C. Stuck, M. Waitz +14
We investigate single photon double ionization (PDI) of helium at photon energies of 440 and 800 eV. We observe doubly charged ions with close to zero momentum corresponding to ele…
Multiorbital tunneling ionization of the CO molecule
J. Wu, L. Ph. H. Schmidt, M. Kunitski +7
We coincidently measure the molecular frame photoelectron angular distribution and the ion sum-momentum distribution of single and double ionization of CO molecules by using circul…
Spatial imaging of the {H_2}^+ vibrational wave function at the quantum limit
L. Ph. H. Schmidt, T. Jahnke, A. Czasch +3
We experimentally obtained a direct image of the nuclear wave functions of {H_2}^+ by dissociating the molecule via electron attachment and determining the vibrational state using…
