Abstract  

Volume diffusion of I anions in the near surface region of copper has been studied by radiotracer technique. The diffusion coefficients were determined for different I coverages on copper employing the Gruzin method of measuring the residual activity. Diffusion annealing was carried out between 303 and 673 K. The distribution of the I species in the diffusion-annealed sample was monitored by noting the residual activity of the specimen upon subjecting it to successive acid-etchings. The simultaneous evaporation losses from the I deposit are reduced by securely holding the sample coupon in between two blank copper coupons using a metal clip.
