  Short-range ordering (SRO) in Fe-Cr has been the subject of a number of
recent experimental and theoretical investigations, as ordering effects are
significant for the phase stability of this technologically important alloy.
Recently, discrepancies regarding the SRO behavior of Fe-Cr have been reported
between results obtained with M\"ossbauer spectroscopy and diffuse neutron
scattering, respectively. As the methodology for reducing SRO parameters from
M\"ossbauer spectra is indirect and relies on the determination of a large
number of parameters, here a new method for directly connecting the M\"ossbauer
effect with SRO is presented. The method is verified using synthetic spectra
derived from Monte-Carlo simulated alloy structures with different SRO
parameters and subsequently it is applied to experimental data obtained from
Fe-Cr alloys. Agreement with diffuse neutron scattering is found at low Cr
concentrations; however, some discrepancies still remain for more concentrated
alloys and possible reasons for these are discussed.
