摘要：

The polymerization transition of liquid sulfur has been observed at the microscopic level, through a change in the local order as a function of the temperature. A diffraction measurement using hot source neutrons (=0.709 A) has been performed to determine the pair correlation function. The third peak of this pair correlation function exhibits a drastic drop with increasing temperature that reflects directly the decrease of the concentration of the sulfur atoms in the S8 rings when the rings are progressively breaking into long chains. © 1990 The American Physical Society.
