Timing double ionization

The attoclock has been used to determine the timing of strong field ionization. For double ionization of argon we found that the ionization time of the first electron is in good agreement with the model predictions, whereas the ionization of the second electron occurs significantly earlier than predicted (DownloadRef. [310] (PDF, 297 KB)vertical_align_bottom) and the two electrons exhibit some unexpected correlation (DownloadRef. [316] (PDF, 569 KB)vertical_align_bottom).
