Abstract: | It has been assumed that in the impurity band metallic regime there exists an energy Ec below which all states are localized and above which all states are extended. This discontinuous model contradicts the results of recent experiments. Using the quantum theory of measurement I resolve these difficulties as my title indicates. |
