Popis:	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.
