Abstract
We measure the low-temperature longitudinal and Hall conductivities in a series of Ge:Sb samples at the approach to the metal-insulator transition. Both conductivities critically vanish with the same exponent of 1, in contradiction to the ratio of 2 predicted by the scaling theory of localization.
