摘要：

Beryllium, tungsten, and carbon are planned as wall materials for the future international tokamak. Although beryllium is not situated in a region submitted to the most dramatic plasma-wall interaction, its reactivity toward hydrogen atom impinging is of fundamental importance. This paper is devoted to theoretical study of hydrogen adsorption on the beryllium (0001) surface based on the first-principles discrete Fourier transform method. Comparison is proposed to former theoretical works and to thermal-desorption spectroscopy.
