Figure 2

Average microscopic cross sections σ̄ for the materials under investigation. The width of the bands indicate the change in cross section due to variation in material composition, as defined in Table 1. The average atomic absorption and scattering cross sections are presented in the left and right column, respectively. For the scattering cross sections, this is the sum of microscopic cross sections for all types of scattering, including those for coherent elastic, coherent inelastic, incoherent elastic and incoherent inelastic scattering
