POSITRON ANNIHILATION CHARACTERISTICS OF HYDRO-GEN-VACANCY COMPLEX IN ALUMINUM
铝中氢-空位复合体的正电子湮没特性

The positron annihilation characteristics of one hydrogenvacancy complex and many hydrogens-vacancy complex in aluminum have been calculated, using the discrete variational method, embedded-cluster model based cm the first-principles and a fully-three-dimensional numerical relaxation technique. The possible location of hydrogen atom in the single vacancy in aluminum is discussed.
