利用同步辐射核共振散射的时域干涉测量（TDI）方法可以研究过冷液体和软物质中约100 ns的微观慢动力学。为了提高TDI效率，我们在传统的TDI方法基础上增加了具有单线穆斯堡尔谱的驱动核吸收体，开发了一种新的TDI方法。利用模拟估计的最优厚度的核吸收体，成功地进行了新的TDI实验，效率比目前使用的传统TDI方法提高了两倍左右。
A time-domain interferometry (TDI) method using the nuclear resonant scattering of synchrotron radiation enables us to study the microscopic slow dynamics of around 100 ns in supercooled liquids and soft matters. To improve the TDI efficiency, we developed a new TDI method by adding another driven nuclear absorber with a single-line Mossbauer spectrum to the conventional TDI method. By using the nuclear absorbers with the optimum thickness estimated by simulation, new TDI experiments were successfully performed and the efficiency was improved about two times that obtained by the conventional TDI method used thus far.
