Abstract
We calculate the corrections to the conductivity and compressibility o f a disordered metal when the mean free path is smaller than the scree ning length. Such a condition is shown to be realized for low densitie s and large disorder. Analysis of the stability of the metallic state reveals a transition to the insulating state in two dimensions.
