摘要：

The diffusivity of tritium in rutile single crystals has been measured parallel to the a and c axes in the temperature range 250-900 °C. Raman-scattering measurements were also made to aid in identifying a nonpolar tritium species involved in the diffusion process. Two species, OT- ions and T2 molecules, are involved in tritium migration. The OT - ions dissociate preceding each tritium jump. Along the a axis the T2 molecules diffuse four orders of magnitude slower than the T + ions associated with OT-. No dependency of the tritium diffusivity upon the rutile defect structure was observed.
