摘要: Abstract Using the RPA we have calculated phonon modes for a model of solid argon without using usual harmonic approximation interatomic pair potential. The procedure permits determination coefficient expansion recourse to additional parameters or further approximations: agreement with experimental values is most satisfactory.
