Mc. Bellissentfunel et al., EVOLUTION OF THE RADIAL-DISTRIBUTION FUNCTION OF LIQUID IODINE ALONG THE COEXISTENCE CURVE, Physical review. B, Condensed matter, 50(9), 1994, pp. 6047-6052
Neutron-diffraction data on liquid iodine at three temperatures on the
coexistence curve are presented. The data show that the strong orient
ational correlations between neighboring molecules, already found at t
he melting point, persist up to the vicinity of the critical point. Th
e A2 effective pair potential model is found to describe satisfactoril
y the structure of the liquid along the entire coexistence curve.
