论文摘要
我们在实验上证明，可以使用电中心颗粒，中子，直接可视化可以分离或占据的目标体积内部的静电场。使用具有敏感偏光法方案的多色，自旋偏振中子束获得电场图像。这项工作可以通过对其他常规探针无法访问的物体中的空间依赖的电场进行成像，从而使电势，电化极化，电荷分布和介电常数的结构的新诊断能力具有新的诊断能力。
We experimentally demonstrate that electrically neutral particles, neutrons, can be used to directly visualize the electrostatic field inside a target volume that can be isolated or occupied. Electric-field images were obtained using a polychromatic, spin-polarized neutron beam with a sensitive polarimetry scheme. This work may enable new diagnostic power of the structure of electric potential, electric polarization, charge distribution, and dielectric constant by imaging spatially dependent electric fields in objects that cannot be accessed by other conventional probes.
