Abstract
The effect of electron binding on the incoherent scattering of gamma rays in uranium in the energy region 320–1332 keV is studied using the total cross sections of Colgate [Phys. Rev. 87, 593 (1952)] and Wyard [Phys. Rev. 87, 165 (1952)]; total photoelectric cross sections of Rakavy and Ron [Phys. Letters 19, 207 (1965)]; and coherent-scattering cross sections based on Thomas—Fermi calculations [W. Brown, Boeing Co. Report D2–125137–1 (Dec. 1966)]. Combining these data, it is concluded that the effect of electron binding on the incoherent-scattering cross section for uranium in the region 320–662 keV exceeds that predicted by the Thomas—Fermi model.
