Abstract
When big heavy ions are implanted in metals, different sites for the impurities are generally found. A substitutional site is possible, as well as defect associated sites. In a general mathematical model we have tried to describe by means of a set of simultaneous differential equations the evolution of an implanted system as a function of time: direct implantation in different sites is possible and transitions from one site to another are induced due to radiation damage effects. With plausible hypotheses for the transition probabilities the solution of the system of differential equations can be obtained. From this solution it appears that the different site populations depend on the implantation parameters: dose, dose rate, temperature, combination host-impurity. Experimental verification of these dependences is in progress or has been performed.
