Berezov V.M., Korepanov V.D., Romanov V.S., Khabibullin B.M.
A deep minimum of the time 7Ί of the NMR of the ammonia protons was observed in the dielectric region (near 150°K) of an electrically-conducting sodium-ammonia solution. Numerical estimates of T{ and of the activation energy have confirmed the model wherein metallic sodium (in the form of a spiderweb) is present in the conducting region and the dissociation of the sodium atoms near 15óçë.
