Abstract
compounds were studied for average Li concentration using photoelectron spectroscopy. Strong evidence is found for the formation of dimers, as well as a second phase. The study suggests that the smallest alkali-metal Li bonds to largely ionically for certain configurations. An investigation of the Li level shows that under certain conditions the energetics favor a backdonation of the transferred electron to the Li ion.
