Pseudopotential theory of thek-dependent plasmon line width in simple metals

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

The nearly free electron pseudopotential theory is used to calculate thek-dependent plasmon linewidth that results from the decay of plasmons via interband transitions. The theory predicts the linewidth to be anisotropic in crystalline systems fork ≠ 0. Local field effects are included, but are found to give very small contribution. A detailed analysis of the behaviour of the linewidth of Al is given and very good agreement with recent experimental data is obtained.
