Abstract : The authors report results of X-ray Compton-Raman scattering experiments in which the incident radiation was scattered by polycrystalline lithium through momentum transfers kappa/kappa(F) = 1.9, 2.5, 3.1, 4.2. In addition to a spectral distribution in the region of the expected Compton peak and evidence of K-X-ray Raman scattering, there is also a prominent feature in the form of a peak near E/E(Fermi) = 1. The appearance of the new peak can be explained qualitatively by considering the conduction band of lithium metal to be composed of hybridized orbital electrons, and it furnishes the first evidence of the existence of an L-X-ray Raman band.
