对镍和铜中缺陷团簇在400 keV ~+离子高温辐照下的动力学行为进行了原位观察。在辐照下的级联团簇的TEM图像记录在录像带上，从级联团簇的初始尺寸和寿命的推导。结果与以前的实验金。从团簇的寿命分布，它的结论是，只有V-团簇形成在铜箔，而V和I-团簇形成在50和100 nm厚的镍箔。
In-situ observation of cascade clusters is performed to examine dynamic behavior of defect clusters in nickel and copper under 400 keV Xe+-ion irradiation at high temperature. TEM images of the cascade clusters under irradiation are recorded on videotapes, from which initial sizes and lifetimes of the cascade clusters are derived. Results are compared with previous experiments on gold. From the lifetime distribution of clusters, it is concluded that only V-clusters are formed in copper foils, while both V and I-clusters are formed in nickel foils of 50 and 100 nm in thickness.
