Abstract
The critical exponents of the metal-insulator transition in disordered systems have been the subject of much published work containing often contradictory results. Values ranging between 1/2 and 2 can be found even in the recent literature. In this paper the results of a long-term study of the transition are presented. The data have been calculated with sufficient accuracy (0.2%) that the calculated exponent can be quoted as s= nu =1.54+or-0.08 with confidence. The reasons for the previous scatter of results are discussed.Keywords
