Abstract
EPR spectra of a molybdenum-related structure defect have been observe d at a temperature of 20 K in CdWO4 scintillator crystal, being as-gro wn ''blue-coloured''. Mo-95 and Mo-97 isotope superhyperfine (shf) spl ittings have been resolved. Further splittings in EPR spectra have bee n interpreted as arising from shf interactions with W nuclea. In the p resent model of the defect, the unpaired spin is localised in the Cd-s ite position and molybdenum replaces one of the neighbouring W atoms. (C) 1998 Elsevier Science Ltd.
