X-ray diffraction studies of stable and supercooled liquid gallium (mp 29.8°C) between 0° and 50°C show no important dependence of internal structure on temperature. Atomic radial-distribution functions were determined for 0°, 10°, 20°, 29.5°, 30°, and 40° and 50°C, from diffraction data to S = 11 Å−1. Diffraction measurements were made in reflection geometry with silver Kα radiation, scintillation counter, and pulse-height analyzer. The density distribution indicates 11 near neighbors; there may be a Ga–Ga complex.
