X. Yi et al., INELASTIC-SCATTERING OF POLARIZED ELECTRONS FROM NONMAGNETIC METALS VIA ELECTRON-HOLE EXCITATION, Solid state communications, 99(4), 1996, pp. 283-287
Inelastic scattering of low-energy electrons from nonmagnetic metals d
ue to electron-hole pair excitation is treated in a distorted-wave fir
st Born approximation including exchange. Screened Coulomb interaction
matrix elements between bulk Bloch states and plane waves (including
elastic scattering in a simple approximation) are evaluated to yield,
for a spin-polarized primary beam, the intensities of electrons scatte
red with and without spin flip. Some basic insight is obtained by calc
ulations for a homogeneous electron gas. Numerical results for Cu(0 0
1) are found to agree fairly well with experimental data and provide c
lear evidence for the importance of elastic scattering processes in el
ectron energy loss spectroscopy. Copyright (C) 1996 Elsevier Science L
