摘要：

Phonon line shapes corresponding to zone-boundary modes in crystalline argon at a temperature close to the melting point have been calculated with a realistic pair potential, using molecular-dynamics simulations. The longitudinal peak is considerably broadened and distorted, in agreement with both experiment and earlier calculations, but now the transverse peak is also substantially broadened, removing an earlier disagreement.
