The constant-${\\bf Q}$ energy scan profiles were collected in the $a^*-c^*$ plane. Three excitations are observed for $E{\\leq}15$ meV. One of the excitations is identified to be magnetic excitation. The lowest magnetic excitation with $E\\sim 0.5$ meV occurs at ${\\bf Q}=(1, 0, 1)$, as observed in KCuCl$_3$. The dispersion relation of the magnetic excitation can be fitted to the dispersion formula derived from the weakly coupled dimer model.
