[EN]因为在大多数功能材料或强相关电子系统中，可以通过掺杂异质元素来控制其性质。因此，要了解掺杂效应，必须对掺杂剂周围的原子成像必不可少。白中子全息术是作者开发的一种新型探测器，用于对材料中掺杂剂周围的轻元素进行原子成像。利用这种方法，作者小组成功地显示了B掺杂Si、B掺杂Mg2X(X：Si，Sn)、Sm掺杂Rb6(R：Yb，La)等材料中掺杂物周围的局域原子图像。作者认为，J-PARC中的白中子全息术将是材料科学的一种新颖而重要的探索。
[en] Since in most of functional materials or strongly correlated electron systems, the properties can be controlled by foreign elements doping. Thus, to understand the doping effects, atomic imaging around the dopant must be indispensable. White neutron holography, which was developed by the authors, is a novel probe for atomic imaging of light elements around a dopant in materials. Using this method, the authors group have succeeded in visualizing local atomic images around dopants in B doped Si, B doped Mg 2 X (X: Si, Sn), Sm doped RB 6 (R: Yb, La) and so on. The authors believe that white neutron holography in J-PARC will be a novel and important probe for materials science.(author)
