Abstract

In any system, the effective exclusion of an atom from the immediate neighborhood of another atom can be used to derive a necessary (but not sufficient) condition which the diffraction pattern of the system has to satisfy. This condition provides a new method of scaling the observed diffraction data from liquids. The currently available x‐ray and neutron‐diffraction data on liquid argon at 84°K are found to differ in a systematic manner, and this discrepancy appears to be beyond the experimental uncertainties of the data. It is demonstrated that the above‐mentioned condition can be used as a reliability criterion as well. Using this criterion, it is found that the neutron‐diffraction data are much more reliable.
