我们使用一种专门为短寿命极不稳定核开发的新型离子陷阱靶进行了演示电子散射实验。本实验以稳定的~(133)Cs离子为靶，完全模拟了电子在短寿命核上的散射。在电子束上仅俘获离子10；{6}的情况下，获得了高于10；{26}cm；{-2}S；{-1}的发光度，成功地测量了弹性散射角分布。这项实验清楚地表明，利用这种靶技术，电子对很少产生的短寿命核的散射是可行的。
We carried out a demonstrative electron scattering experiment using a novel ion-trap target exclusively developed for short-lived highly unstable nuclei. Using stable 133Cs ion as a target, this experiment completely mimicked electron scattering off short-lived nuclei. Achieving a luminosity higher than 10;{26} cm;{-2} s;{-1} with around only 10;{6} trapped ions on the electron beam, the angular distribution of elastic scattering was successfully measured. This experiment clearly demonstrates that electron scattering off rarely produced short-lived nuclei is practical with this target technique.
