Abstract
A simple model is proposed for the diffusion-controlled release of radioactive nuclei implanted into a metal. Experiments using a tungsten target bombarded by 25 keV 135,137–141Xe1+ ions have been conducted in order to make a comparison with this model. Experimental results agree with the expected behaviour and the Arrhenius relation is obeyed over the temperature range with an activation energy EA = 110 kJ/mole and a pre-exponential factor D0 = 1.4 × 10−11 cm2/s.
