Main panel: 2D false-color map of ion hit radius R versus TOF for the N+ and [{\rm{N}}_{2}^{2+}] ions, from a PEPICO measurement with N 1s photoelectrons of N2 at hv = 4.9 keV. A false coincidence 2D map has been subtracted. The blue rectangle marks the region of the [{\rm{N}}_{2}^{2+}] ions, shown in detail in inset (a). Inset (b) shows this region for the false-triggered events. Solid lines represent simulated R(TOF) curves for N+ with 3.75 and 4.95 eV kinetic energy (green) and for [{\rm{N}}_{2}^{2+}] with 176 meV of recoil energy (magenta).
