Electron attachment to Br/sub 2/ and HBr has been studied over a range of E/P values using a high-pressure electron-beam-sustained gas-discharge apparatus. Experiments were performed in gas mixtures containing the attaching species and a large excess (> or =99%) of N/sub 2/ which was included to control the electron temperature. Values of the dissociative attachment rate constants at an average electron energy near 1.0 eV for Br/sub 2/ and HBr were found to be 1.0 x 10/sup -10/ and 8 x 10/sup -10/ cm/sup 3//sec, respectively. Using the known electron energy dependence of the dissociative attachment cross section, the magnitude of the dissociative attachment cross section for HBr was estimated.
