    • Abstract


      Plasmon dispersion in Al is estimated using the expression for the dynamic structure function,Spl(K,ω), corresponding to the plasmon excitations in a many-electron system derived earlier. An evaluation of its plasmon linewidth is also presented. It is observed that for Al both the dispersion and linewidth agree fairly well with experiments.
