Dispersion of phonons in a Be single-crystal along [00ζ] in the first and second Brillouin zones. Red circles with error bars are the results of this current study and black squares are taken from previous inelastic neutron scattering measurements (Stedman et al., 1976; Alatas et al., 2008). The black line denotes the energy resolution (26 meV) of the current work. |
