Figure 14
Photoelectron–photoelectron–photoion coincidence (PePePiCo) map for two-photon double ionization of neon at ℏω = 44 eV. The ion TOF is plotted on the horizontal axis. The vertical axis shows the sum of the TOFs of the first and second detected electron impinging on the detector. In total, 1.6 × 107 FEL pulses were taken to produce the histogram. The figure is taken from Schmid (2018). |
