Hydrogen and vacancies in the tokamak plasma-facing material beryllium
Description
Within the framework of the density functional electron theory in local-density approximation and the ab initio pseudopotential method the properties of vacancies and hydrogen atoms near vacancies in beryllium are calculated. The vacancy formation energy is 1.13 eV. The hydrogen atom is located off-centre, i.e., on a hexahedral interstitial site near the vacancy. (orig.)
