Figure 3

Measured structure factor $S(Q)$ of a Ni melt at $T=1435\mathrm{K}$ in the range $4.5{\AA }^{-1}<Q<11.4{\AA }^{-1}$ (dots), and simulated $S(Q)$ by assuming clusters with different symmetries prevailing in the melt: icosahedra (dashed line, $⟨r_0⟩=2.38\AA$, $⟨\delta r_0^2⟩=0.029{\AA }^2$, $X=0.99$), dodecahedra (solid line, $⟨r_0⟩=2.42\AA$, $⟨\delta r_0^2⟩=0.026{\AA }^2$, $X=0.95$), fcc clusters (dotted line, $⟨r_0⟩=2.45\AA$, $⟨\delta r_0^2⟩=0.032{\AA }^2$, $X=0.99$). The inset shows the results of the simulation under assumption of icosahedral clusters (solid line) together with the contributions of the two shortest interatomic distances within these clusters: distance of the central atom to the atoms on the shell $⟨r_0⟩$ (dashed line) and next neighbor distance of atoms on the shell $⟨r_1⟩$ (dotted line).Reuse & Permissions
