Abstract

The paramagnetic resonance of Fe3+-ions in cubic synthetic ZnS crystals has been observed after uv-irradiation at 77 °K. The spectrum was analysed with g=2.0194 ± 0.0003 and |α |=0.0128 ± 0.0001 cm-1, where 3 α is the zero-field splitting. The hyperfine interaction constant of the 2.2% isotope Fe57 was found to be |A|= 0.00078 ± 0.00005 cm-1. The splitting of the central fine structure line revealed the existence of submicroscopic twins. Two additional epr-lines have been observed after crushing and after annealing the crystals in zinc vapour.
