Figure 1. The I554 Angular function shown with the axes used to define the function. For the parameterisation of the (e,2e) Differential cross section, the z-axis is chosen as the incident electron beam direction. The x-axis is chosen to lie in the Detection plane of the analysers. The colour scheme reflects the sign of the function. PURPLE indicates the function is POSITIVE whereas RED indicates that the function is NEGATIVE.
