摘要：
Accurate neutron-diffraction measurements on saturated liquid iodine, up to Q = 16 angstrom -1, at T = 409 K are presented. The intermolecular structure factor has been derived and a study performed on the presence of orientational correlations and their contribution to the intensity distribution. The experimental intermolecular pair correlation function has been compared with the results of a simulation performed using the anisotropic atom-atom pair potential proposed by Rodger, Stone, and Tildesley [Mol. Phys. 63, 173 (1988)], giving excellent agreement. A comparison with previous neutron and x-ray data is also discussed.
