Figure 2. Attenuation in He. Experimental data from Azuma et al. [40]. Chantler [16] (dash-with-cross) agrees with experiment, as compared to Scofield unrenormalized (dash-dot-dot-dot) or renormalized (short dash, Saloman, Hubbell, and Scofield) [34]. Uncertainty in scattering dominates above 11 keV. Scattering component in the dash-with-cross curve is derived from Saloman, Hubbell and Scofield [34], in turn from Brown in Hubbell et al. [12].
