53. A valuable approximation to this problem has been developed in Ref. 27 . However, this analysis, performed only at RT, relies on the isotropy of the diffusion of single vacancies on Ge(111) -c(2 X 8). The inclusion of anisotropies in the equations worked out by these authors would imply such huge experimental statistics that it becomes, in practice, unfeasible for this reconstruction.
