| Abstract: | The positron annihilation characteristics of vacancies in iron in different phases have been calculated by using the discrete variational method and embedded-cluster model based on the first-principle and two-component density-functional theory.The effect of lattice-expansion and lattice-relaxation on the positron annihilation characteristics is discussed. |
