摘要：

Ion implantation is used to introduce lead into the mineral apatite. Diffusion profiles are obtained using Rutherford backscattering (RBS) and the results fit with a model to determine D. Results for apatite over the temperature range 600-900 ° C show agreement with earlier results obtained by traditional geological techniques. This suggests that radiation damage induced by ion implantation has little effect on diffusion in this case. This approach is both simple and useful in studying diffusion over a temperature range of geologic interest without inordinate annealing times. © 1990.
