| Research Abstract |
Molecular dynamics simulations of helium atoms in Fe were performed. As a result, the new knowledge about the growth process of a helium bubble was acquired.
The interaction of atomic hydrogen with Be_<12> Ti has been also studied by means of first principles electronic-structure methods. Hydrogen atoms accommodated with in twenty different sets of lattice site, resulting in solution energy of 0. 1 eV～0. 7 eV.
