| Abstract: | Nominally pure BaF 2 single crystals were investigated at 77 v K with optical absorption and electron paramagnetic resonance to understand the mechanism of radiation damage. We find that X-irradiation at 77 v K of undoped BaF 2 produces V k - and F -centres having absorption bands at 3.4 and 2.3 v eV respectively. |
