Abstract
The famous nonmetal-to-metal transition in Na–ammonia solutions is investigated in nanoscale solution droplets by photoelectron spectroscopy. In agreement with the bulk solutions, a strong indication for a transition to the metallic state is found at an average metal concentration of 8.8 +/- 2.2 mole %.The smallest entity for the phase transition to be observed consists of approximately 100–200 solvent moleules. The quantification of this critical entity size is a stepping stone toward a deeper understanding of these quantum–classical solutions through direct modeling at the molecular level.
