用一种特殊设计的x射线衍射仪，在50、100和150摄氏度下获得了液态汞的干涉函数。结果的重要特征是第一峰高度随温度的快速变化。通过将观测到的干涉函数与硬球模型的干涉函数进行匹配，发现液体的等效堆积密度从50℃时的0.42变化到150℃时的0.32，根据这些堆积密度值计算了每个温度下的可压缩性，所有这些值都高于已发表的实验值。结果表明，随着温度的升高，离子间排斥力可能增大。
Interference functions from liquid mercury have been obtained at 50, 100 and 150 degrees C, using a specially designed X-ray diffractometer. The important feature of the results is the rapid change of first peak height with temperature. By matching the observed interference functions to those from a hard sphere model it is found that the equivalent packing density of the liquid changes from 0.42 at 50 degrees C to 0.32 at 150 degrees C. From these values of the packing density the compressibility has been calculated at each temperature and all are higher than the published experimental values. It is concluded that there may be an increase in the inter-ionic repulsive force as the temperature increases.
