Evidently , the probability that a vacancy will exchange with a solute on its first
jump from a neighboring site is w2 / ( w2 + 4w , + 7w3 ) . Similarly , the probability
that the vacancy will exchange with a solvent neighbor in one jump is 4w , / ( w2

To introduce these factors into the flux , one must start with the probability for the
first jump to be parallel or antiparallel to the field which is applied in the + x
direction . This is followed by the tendency for the jump completed to contribute to
the ...

Let this probability be U + . 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
