NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. X-ray diffraction studies of stable and supercooled liquid gallium (m.p. 29.8[degrees]C.) between 0 and 50[degrees]C. show no important dependence of internal structure on temperature. Atomic radial distribution functions were determined for 0, 10, 20, 29.5, 30, 40, and 50[degrees] from diffraction data to S=11[...]. Diffraction data was obtained in reflection geometry with Ag K-alpha radiation, scintillation counter, and pulse-height analyzer. The sample was contained in a sealed plastic cell with transparent walls. A supporting assembly provided temperature control within 0.1[degrees]C. and a transparent plastic X-ray window which permitted visual inspection of the sample surface. Arguments are presented in favor of normalizing scattered intensities to independent scattered intensity at high S values. The method of inversion is based on a single, piecewise polynomial approximation to the scattering function i(S) for each temperature.
