Fig. 3

Constant-energy slices of scattering intensity. a-c and d-f are the results obtained using the neutron scattering data measured with E i = 7.74 and 15.16 meV, respectively. The x and y axes are the components of Q parallel to (H, H) and (−K, K), respectively. Integrated energy ranges are shown in the figures. Solid white lines are Brillouin zone boundaries
