Tribromofluoromethane (CBr₃F) is a polar, electron-attaching gas that has 120 electrons. Its electronic polarizability is 10.80 × 10⁻⁴⁰ F m² (Barszczewska et al., 2004).

71.1 ATTACHMENT RATE CONSTANTS

Dissociative attachment of electrons occurs with the formation of both Br⁻ and ${\text{Br}}_2^{-}$ ions (Sunagawa and Shimamori, 1997) and the peak of the cross section occurs at zero energy. Table 71.1 gives the attachment rate constants. Figure 71.1 shows the attachment rate constants as a function of mean energy of the electron swarm.

71.2 ATTACHMENT CROSS SECTIONS

Table 71.2 and Figure 71.2 show the attachment cross sections for CBr₃
