摘要: The thermodynamic properties of solid argon, krypton, and xenon have been calculated for a two-body central force potential. Anharmonic contributions due to thermal expansion taken into account via quasiharmonic calculation based upon the Born Huang method homogeneous deformations. nonarbitrarily adjustable parameters Morse potential obtained from solid-state bulk in recursive refinement procedure. For those sensitivity dependent dilatation lattice calculations become valid only temperatures less then $\frac{1}{3} {T}_{M}$.
