Observation of energy superstructure in lithium
Kobzar' Yu. M. , Bodnar N. N. , Kozych V. Ya., Kovtun V. G.
The electron-photon emission of lithium at photon energies 0.23-3 eV have been studied. Several structural features have been detected for the first time in the emission spectrum of lithium. On the basis of these features it was assumed that charge-density waves produce an energy superstructure.
