X-Ray Compton Profiles of Li and Na: Theory and Experiments

Abstract: A general discussion is presented of x-ray Compton profiles for conduction electrons in metals. A formalism that includes both the interelectron Coulomb interaction and the electronion interaction is then introduced. X-ray-scattering measurements of the Compton profiles of single-crystal Li and polycrystalline Na were carried out at room temperature. There is substantial agreement bebveen our experimental data and the theoretical predictions.

“…Being a low-Z material, lithium has been the subject of Compton studies since the early days of x-ray Compton scattering [6]. Recent high-resolution experiments have been conducted on lithium and Fermi surface signatures have been investigated either by analyzing first and second derivatives of the Compton profiles [7] or attempting a reconstruction of the momentum distribution [8].…”

“…The electron momentum density is highly anisotropic, the high momentum components (HMCs) are small but important. The momentum distribution of Li has been investigated in the past, both theoretically and experimentally, by several workers [16][17][18][19][20] with the available state-of-the-art procedures. Recently, Sakurai et al 13 In the present paper, we use full-potential linearized augmented plane wave method for the computation of CP which have been corrected to include the correlation effects not accounted for within LDA, alongwith one and two dimensional angular correlation of positron annihilation radiation (1D-and 2D-ACPAR) which include corrections due to electron-positron correlation effects.…”

“…18 The partial profiles are isotropic and thus are well accounted for by the free-electron-like sp bands. 19 The diameter of the Fermi sphere has been estimated from the number of electrons under the parabolalike profile. Comparing the sizes between the Fermi sphere and the q-BZs, it has been concluded that the Hume-Rothery mechanism plays an important role in i-Al 6 Li 3 Cu but not in d-Al 72 Ni 12 Co 16 .…”
