A quenched equilibrium state of a ⁶⁵31.1 at. % Zn single crystal was investigated by elastic diffuse neutron scattering. The short-range order intensity showed maxima that could be related to the flat portions of the Fermi surface perpendicular to the 〈110〉 directions. Effective pair potentials Vₗₘₙ were determined from 71 short-range order parameters αₗₘₙ obtained from a fit to the diffuse intensity. Furthermore, 40 linear displacement parameters were also extracted. A dominant V₁₁₀ of {~}18 meV was obtained. Based on a Monte Carlo simulation, an ordered low-temperature phase Cu₃Zn with the DO₂₃ structure and a critical temperature of {~}330 K is suggested.
