Uranium hexafluoride (UF₆) is a large inorganic molecule with 146 electrons. It has an electronic polarizability of 13.91 × 10⁻⁴⁰ F m², is nonpolar, and has an ionization potential of 14.00 eV. The dissociation energy (UF₅–F) is 3.0 eV (Compton, 1977). There are six vibrational modes as shown in Table 92.1.

92.1 DIFFERENTIAL SCATTERING CROSS SECTIONS

The measured differential scattering cross sections in the energy range 10–75 eV (Cartwright, 1983) are shown in Figures 92.1 and 92.2. These supersede ...
