Our approach has an additional advantage of allowing to selectively switch off different contributions from the parent ion (such as the remaining electron or the nuclear charge) and thereby investigate in detail how the final electron angle in the attoclock experiment is influenced by these contributions. We find that the bound electron exerts a significant effect on the final electron ","authors_text":"A. Chen, A. Emmanouilidou, A. S. Landsman, C. Hofmann, U.
