The differential scattering cross sections in Xe are shown in Table 93See Figure 92 for graphical presentationThe dominant feature of the differential cross section is the diffraction pattern peaks and valleysAt low energy (~1 eV), two valleys are observed; with increasing energy (~20 eV), three shallow minima are observed A further increase in energy (~60 eV) increases the minima to four, clearly demonstrating the dominance of the l = 4 partial waveSome of the minima are not evident or become less pronounced at higher energies and obviously many partial waves contribute to the observed pattern (Raju, 2005)
