Popis:	We have performed different neutron diffuse scattering measurements in ${\text{Fe}}_{1\ensuremath{-}x}{\text{Cr}}_{x}$ solid solutions, in a concentration range $0lxl0.15$, where the atomic distribution shows an inversion of the short range order. By optimizing the signal-background ratio with respect to a previous study, we obtain an accurate determination of the concentration of inversion ${x}_{0}=0.110(5)$. We determine the near-neighbor atomic short range order parameters and pair potentials, which change sign at ${x}_{0}$. The experimental results are compared with previous first-principles calculations and atomistic simulations.
