摘要

核辐射能使固体晶格损伤，引起其电磁学、光学及力学参量的改变。在某些金属表面通过带电粒子辐射或离子注入，可提高材料的抗腐蚀性能、抗氧化性能和耐磨性能。一些半导体材料，通过重离子或中子辐射，可产生一种新的杂质元素，这种方法成为制备半导体器件的新工艺。所以对辐射损伤及其变性的机理研究很有价值。现在国际上正采用各种方法，如扰动角关联、电子显微镜、沟道效应、穆斯堡尔效应、中子散射及正电子湮没等方法，企图从不同的侧面来揭示辐射损伤的微观特性。

Abstract

The TDPAC (time differential perturbed angular correlation) method is used to investigate the radiation damage induced by electrons in metal material Ag and Ni. The energy and flux of electron are 1 MeV and 2.5×10

~10

electron/cm

respectively. Two kinds of defects were found. One of them is stable

and the other is in nonequilibrium diffusion process and depends on the total dose of radiation.
