<jats:title>Abstract</jats:title><jats:p>Irradiation of AgBr:Te or AgBr:Se with green light at about 180°K produces a paramagnetic centre. It will be shown by investigation of the angular dependence of <jats:italic>g</jats:italic>‐values, superhyperfine structure, and hyperfine structure that the centre has orthorhombic symmetry, consists of two equivalent impurity anions and strongly interacts with two bromine ions.</jats:p>
