Upon the addition of Li to anhydrous ammonia, the famous Li-Ammonia solutions form through an intriguing metal-insulator transition. These have been studied intensely for many years (including by quasielastic neutron spectroscopy), and yet no clear explanation for their physicochemical properties exists.Recent theoretical work suggests intriguing H-H interactions in the liquid, and particularly 'strange' interactions in the solid phases. We propose a large DINS experiment, as detailed in this proposal, to explore the state of the proton in these systems. We not ehtat VESUVIO is unique in being able to do this, and also that due to the distribution of masses in the system (H, Li and N) being easily separable on VESUVIO, addition information on the Li and N nuclear momentum distributions across this range of systems will be able to be collected simultaneously.
