a–c, Experimental ion yields are obtained by fitting a 2D Gaussian to each peak in the respective Newton plots (Fig. 3). The experimental error bars represent an estimate of the systematic error introduced in the fitting (Methods). The experiment is insensitive to neutral fragments. d–f, Corresponding theory results are shown with the statistical error derived from the finite number of trajectories. The fluences used in the calculations are 0.75 × 1011 (d), 1.80 × 1011 (e) and 2.30 × 1011 (f) photons μm–2.
