X光汤姆逊散射技术是研究温稠密物质离子-离子强关联效应的有力工具。但在最近的实验中，测量的离子特征峰偏离理论模型的计算，初步研究表明这种偏离可能与非平衡效应有关。本项目拟采用硬X光等容加热中Z材料固体靶的方法产生低温强离子-离子关联的温稠密物质，并利用X光汤姆逊散射技术多角度观测温稠密物质的离子特征峰，通过与理论计算结果的对比，检验非平衡效应对离子特征峰的影响，加深我们对温稠密物质内部离子-离子强关联效应的认识。

The X-ray Thomson scattering is a powerful technique in investigating the strong ion-ion correlations in warm dense matter (WDM). However, the ion feature measured from a recent experiment deviates from several theoretical calculations, which probably result from the nonequilibrium effect. The present project will generate low-temperature mid-Z WDM with strong ion-ion correlations by isochorically heating solid target, and observe the strong ion feature of WDM using x-ray Thomson scattering measurements at various scatter angles. By comparing with the theoretical calculations, this work will help to figure out the influence of nonequilibrium effect on the ion feature, and to deepen our understanding of the strong ion-ion correlations in WDM.
