## Abstract The change of the EPR line width, shape, and angular dependence of the halfwidth of Cr^3+^ ions in ZnWO~4~ is investigated in the temperature range from 4.2 to 1200 Β°K. It is shown that the EPR line broadening at high temperatures is due to the spinβphonon interaction. Twoβ and fourβpho
In this paper, the absorption spectrum of PbWO 4 :Cr 3+ crystals is measured at room temperature in the wavelength range from 340 to 520 nm. The d-d transitions of Cr 3+ ions in PbWO 4 crystals with tetragonal symmetry are calculated by the crystal-field theory. The theoretical results are in good a
