The electric field gradient at Zr sites has been measured by time-differential perturbed angular correlations in amorphous and crystalline ${\mathrm{Zr}}_{68}$${\mathrm{Hf}}_2$${\mathrm{Cu}}_{30}$ alloys. The results support a dense random packing of atoms and discard any kind of regular atomic arrangements in the amorphous alloy.
