Figure 3. Attenuation in Cu (Z = 29), represented by Im (f) = f2. [�/ρ] (in cm2/g) = f2 (e/atom) � 6.622 02 � 105. Experimental data from Saloman, Hubbell and Scofield [34]. Chantler [16], Scofield theory and even the smoothed structure of Henke et al. [32] agree with uncertainties of available experiment. In this case, the qualitative near-edge structure is the same for all tabulations, except for the apparent offimmion of the LIII edge in the Henke curve.
