Figure 2: Angle- and energy-resolved electron spectra and circular dichroism.

Double differential cross section (a,b) and differential circular dichroism (c,d) in He 1 s photoionization at low-NIR laser intensity (7.3 × 1011 W cm−2). Experimental results are shown in the upper panels, the results of simulations in the lower panels. The respective intensities are indicated by the colour scale on top of the graphs.
