Abstract
We present measurements of the optical reflectivity and microwave dielectric constant of Na-NH3 solutions in the concentration range around 4 mol-% metal, i.e. at conditions where the transition from localized to itinerant electronic states takes place. The concentration and temperature dependence of the optical constants approaching the metal-nonmetal transition is discussed.
