[en] EPR spectrum of Gd3+ ion in ThO2 monocrystal was investigated in the temperature range 119-568 K. Spectrum had cubic symmetry with the slight admixture of lines of axial symmetry. The strong dependence of b40 on temperature was observed. It was interpreted as a result of the change of inter-ionic distance. (Z.M.)
