N2 - The optical gap, Eg, of amorphous indium-oxide films is measured as a function of static disorder near the metal-insulator transition. On the insulating side of the transition the optical gap obeys a scaling relation, ΔEg = -E*Δg where E* is of the order of the Fermi energy of the given sample and g≡KFl. These results are ascribed to the continuous shift of the mobility-edge in the conduction band with disorder.
