We investigated all possible stable interstitial positions of the helium atom in the hcp lattice of beryllium by methods ab-initio simulations. We studied of helium-vacancies complexes in the hcp beryllium and calculate the energy of formation and migration of vacancies. We studied cases of finding of helium in the hcp lattice sites, in different interstitial positions and in the divacancy complexes. We found that absorbed helium in hcp beryllium promotes the formation of divacancies. Product Description popup.authors Бакай О.С. Бар'яхтар В.Г. Калькута С.А. Тимошевський А.М. Яблоновський С.О.
