The whole-atom integral incoherent-scattering cross sections of elements Na, Cl, K, Cu, Br, Rb, Ag, Cd, I, and Hg have been derived with the aid of the mixture rule from the incoherent-scattering cross sections of their simple halides. The cross sections of the halides are extracted from their total attenuation cross sections measured by performing transmission experiments in a modified narrow-beam setup. The results are found to be in good agreement with the values assembled by Hubbell et al. [J. Phys. Chem. Ref. Data 4, 471 (1975)] that are interpolated to 661.6 keV.
