Abstract:
The inelastic light scattering by intraband electronic excitations in metallic lanthanum hexaboride has been studied in the temperature range of $10$–$300$ K. General agreement has been obtained between the measured spectra and the spectra calculated within the band theory taking into account the renormalization of electron energies owing to electron-phonon scattering. The electron-phonon coupling constant $\lambda$ and electron relaxation frequency $\Gamma$ have been estimated. The dependence of the electron self-energies on the direction and magnitude of the wave vector has been revealed, implying the anisotropic electron-phonon interaction or the contribution from other electron scattering mechanisms.
