Draw out of the predicted interatomic force
M. Inui, Graduate School of Integrated Arts and Sciences, Hiroshima University, et al.
The research group reported that the IXS experimental results for liquid Bi clearly show a distinct inelastic excitation of the acoustic mode. This resolves the previous disagreement in the literature. Those researchers said, "Consistent with ab initio calculations of liquid Bi, the dispersion curve was nearly flat from 7 to 15 nm [to the negative 1 power]."
They also mentioned, "A long-range force is needed to reproduce the flatness of the dispersion curve, and the long-range force has to strongly be related to a local structure consisting of shorter and longer bounds in the liquid."
This research group demonstrated a possible mechanism for the unusual dispersion of liquid Bi.
