After the tracer - vacancy exchange , the vacancy must be on one of these four
sites . Consider that the vacancy directly returns to the tracer , this probability
contributes to Pa . Furthermore , the probability that the vacancy wanders off but ...

That is , when a new vacancy ( one which has not exchanged with the tracer )
becomes a neighbor with the tracer and makes a diffusive jump , P is the net
effective probability that the next tracer jump will return the tracer to the original x
plane ...

The flux will be related to the effective tracer jump rate vet . Vet = Væ + U + Also ,
U + is calculated from Pa + and pt . One of the vacancies contributing to Va +
arrived at the tracer . The vacancy may cause a tracer displacement of ( 1 ) + d
