The radiation-enhanced and thermally driven migration of C into the crystals was studied by means of the nuclear reaction, 12C(d,p)13C, and secondary ion mass spectrometry, respectively. The associated diffusivities were estimated to be equal to 1.4 x 10-12 to 1.8 x 10-12cm2/s, for radiation-enhanced diffusion at 300 to 370K, and to 1.0 x 10-15cm2/s at 1100K for thermally driven migration.
