Re-emission curves and thermodesorption spectra were measured for D ions which had been implanted into this material. The thermodesorption spectra consisted of several peaks at temperatures ranging from 400 to 1100K. The re-emission curves could be described by a simple mathematical model which included the effects of diffusion, second-order thermodesorption and defect trapping. The recycling factor and defect-trapping factor were found to depend exponentially upon the temperature, at temperatures above 600K. They deviated from this behavior at room temperature. It was supposed that radiation-enhanced and thermally-activated processes predominated at room and high temperatures, respectively.
