Positions of the first peak in the reduced pair distribution functions, G(r), for liquid AuGa2 (squares) and ratio of the second to first peak positions (circles). The dashed lines indicate the ideal ratio determined for a simple close-packed hard sphere-like structures (r2/r1 ≈ 1.91) and for an ideal tetrahedral structural unit (r2/r1 ≈ 1.63)8. The errors in peak positions are in the range of ±0.002–0.018, smaller than the corresponding symbols.
