A Note on the Analysis of Liquid X-Ray Diffraction Patterns

Abstract

The corrected intensity curve given by Eisenstein and Gingrich for the diffraction of x-rays by liquid argon has been subjected to four different fittings, one of them including a weak fourth peak, to determine how sensitive the atomic distribution curve is, to errors in fitting. An analysis has been made for these four cases. The first peak of the atomic distribution curve has about the same shape in each case, the area under this peak varies by less than ten percent, and the position of its maximum remains constant to within about one and one-half percent. The small secondary peak becomes a plateau by the introduction of a weak fourth peak in the intensity curve.
