## Abstract Two sets of paramagnetic species having a spectroscopic splitting factor slightly higher than the free electron value are produced in CaWO~4~ doped with copper after irradiating the crystal with ultraβviolet light. One set of lines is identified as being due to a hole trapped at a singl
