Abstract
At low vacancy concentrations in crystals the motion of an atom due to the vacancy mechanism is a correlated walk during the sequence of atomic jumps arising from an encounter of a specific atom and a specific vacancy. It is shown that the diffusion correlation factor and the atomic displacement probability of the correlated walk of an atom in a cubic crystal may be simply obtained from some well known functions of random walk theory.Keywords
