X irradiation of solid KXO/sub 3/, X = Cl, Br, is shown to produce complex defects of composition (XO/sup -/, O/sub 2/) and (XO, O/sub 2/). (XO/sup -/, O/sub 2/), which is produced also by UV irradiation of KXO/sub 3/, is formed during and after x irradiation in a reaction between electrons, self-trapped as XO/sup 2 -//sub 3/, and holes, self-trapped as XO/sub 3/. (XO,O/sub 2/) is shown to arise in the oxidation of (XO/sup -/,O/sub 2/) by reaction with XO/sub 3/. In KClO/sub 3/, the complex (ClO/sub 2/,O/sub 2/) is formed also, possibly in a reaction between ClO/sub 3/ and (ClO/sup -//sub 2/,O/sub 2/) .
