| 英文摘要 | Pure nickel foil was irradiated with multiple-energy helium ions at room temperature. Using elastic recoil detection (ERD), the depth profile of helium concentration in nickel foil after the irradiation was investigated. Result showed that very little helium atoms distributed in the regions near two free surfaces, indicating the occurrence of helium release. Interestingly, the release clues of open cracks probably resulted from the generated surface stress were observed by scanning electron microscopy (SEM). Furthermore, the shifting of X-ray diffraction (XRD) diffraction patters towards the lower diffraction angles revealed the occurrence of lattice swelling. The results of slow positron annihilation spectroscopy (PAS) experiments suggest that abundant vacancy type defects were introduced in the helium-irradiated nickel foil. The elastic strains caused by the formation of helium-vacancy clusters in the lattice were assumed to be responsible for the lattice swelling. |
