Abstract: A model is proposed to calculate the average probability and the average size of the localisation domain for an electron being localised at a given site in a Cayley tree lattice. The numerical results are presented in the limit of weak disorder in the case of the Cauchy distribution for site energies. Attention is paid to the states near the mobility edge in the localised regime. In particular, features exhibited in the linear-chain case are observed for the first time for higher dimensions.
