Figure 2
Dispersion curves calculated for the semi-empirical models (with initial parameters) used in this work, compared with experimental triple-axis spectrometer data gathered by Stedman & Nilsson (1966BB34) at 80 K (red points). Heavy black lines represent the LJ 12-6 model, heavy grey lines the Mei-Davenport EAM, heavy yellow lines the NP-B EAM and thin black lines the Sutton-Chen EAM.  [article HTML]
