✦ Synopsis

In synthetic zircon crystals grown from Li20-Moo3 and simultaneously doped with U,O. and either Euz03 or Tbb203. Mo5+ was detected by EPR after UV illumination at 15 K. The site symmetry is monoclinic, but the deviation from orthorhombic symmetry is very small. MO'+ is most likely formed as a radiation defect of low thermal stability from Moe+ initially incorporated on Si sites. The g factors and satellite hypertine splitting constants for the mixture of "MO and 9'M~ nuclei were determined.
