ABSTRACT
Deuterium bromide (DBr) has properties very similar to hydrogen bromide (HBr) as expectedThe attachment rate constant for the molecule is 31 × 10−17 m3/s (Christophorou et al, 1968)The attachment cross sections are very similar to that for HBr, the ion formed being Br− due to dissociative attachmentTable 141 shows the electron attachment data for DBr and HBr
Table 142 and Figure 141 show the attachment cross sections for DBr
