Mottgratios of the density of states for Na-NH3

Mott ratios of the density of states have been obtained for Na-NH3 using the theory recently developed by Mott (1971) and by Friedman (1971), and the conductivity and Hall constant data of Kyser and Thompson (1965), for concentrations greater than ∼2 mole % metal. These are given as evidence of the self-consistency of g derived from different transport measurements and of the physical significance of g in describing the MNM transition that the system undergoes.
