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 (1966  ) 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. |
