ELECTRONIC STRUCTURE AND DEFECT SPECTROSCOPY OF POINT DEFECTS IN METALS
金属中点缺陷的电子结构和缺陷谱

The electronic structures and positron annihilation lifetimes for vacancy-like defects, H-impurity and vacancy-H, vacancy-He complex in the transition metals Cr, Fe, Ni and the noble metal Cu have been calculated, using the density functional formalism and local density approximation based on the jellium model. It is shown that positron lifetime studies can produce fingerprint speetroscopy of defect of various sizes and structures in metals.
