摘要: We present a study of the ambient and low-temperature dynamics on single-crystalline sample NbSe3 using meV-resolution inelastic x-ray scattering. Two phonon branches (LA, TA 1 ) propagating along systems quasi-one-dimensional direction b* have been determined. The data indicate absence Kohn anomaly, similar to case (TaSe 4 2 I, but at variance with other charge-density-wave (KCP, K 0 . 3 (MoO investigated so far.
