| Abstract: | Abstract ESR investigations of gamma-irradiated sodium selenate in powder form indicates a number of paramagnetic species as SeO? 2, SeO? 3, and SeO? 4, identified on the basis of their g-tensors. The appearance of a new ESR line at g = 2.0260 attributed to the SeO? 4 radical indicates a possible structural phase transition at 165 K in Na2SeO4. |
