## Abstract Like the EPR line of the fundamental state of the F centre in most of the alkali halide crystals, the line attributed to the relaxed excited state detected optically for F centre pairs is also Gaussian in shape. That is explained by an inhomogeneous broadening due to hyperfine interacti
## Abstract The electron paramagnetic resonance of F centres in the ground and excited states has been optically detected in the following alkali halide crystals: NaCl, KF, KCl, KBr, KI, RbBr, and RbI. A decrease of the radiative quantum efficiency of the F centre luminescence is observed when micr
## Abstract It is shown that a better theoretical formulation of the properties of the U~2~ centre in the alkali halides is given in terms of ligand field theory rather than the approach usually adopted, which consists of an application of the techniques employed by Gourary and Adrian [5] in their
