Intrinsic paramagnetic defects in undoped zinc tungstate single crystals have been observed by ESR after electron irradiation at room temperature. The only observed hole-type defect is attributed to a hole trapped at an O2- ion near a zinc vacancy. Two electron-excess centers are each due to a single electron trapped at an oxygen vacancy, where the defects differ in the oxygen vacancy positions. All of the defects exhibit superhyperfine interactions with neighboring 183W nuclei. Spin-Hamiltonian parameters are reported and discussed.
