Byberg, J R

The ESR spectra of primary electron-excess defects in KClO/sub 4/ and KBrO/sub 4/ crystals irradiated with x rays at 26 K indicate that trapping of electrons on ClO/sup -//sub 4/ leads to immediate expulsion of O/sup -/, whereas BrO/sup -//sub 4/ may accept an excess electron, forming a doubly charged anion BrO/sup 2 -//sub 4/. The thermally activated formation of O/sup -//sub 3/ involves in both cases addition of O/sub 2/ to the primary electron-excess defects. Hence, BrO/sup 2 -//sub 4/ is chemically equivalent to O/sup -/.
