详细叙述用剩余强度法测定扩散系数的方法。测定了Co~(60)在铜单晶体中的扩散系数。并对一些可能产生的误差来源作了分析。
The experimental details of the determination of diffusion coefficients by the"residual activity" method are described. The possible sources of errors are discussed.The diffusion coefficient of Co~(60) in copper single crystals determined by this method isgiven as D=0.84 exp (-52,100/RT) cm~2/sec which is in good agreement with the resultsof Macklietl and Sakamoto obtained by "sectioning method".
