First we calibrated the spectrometer in atmosphere using the peak-channel of 241Am, Thc-c’ standard radioactive source while the window diameter isφ3. 0 mm and gained following formula with respect to the energy (E/MeV) ofαand the channel (Ch): E=1. 507 55 + 0. 016 31×Ch+6. 235 24×10-6×Ch2 So, when E=5. 486 MeV, the Ch is equal to 221. 493. When changing the diameter of incident window toφ1.5 mm, we find the peak-channel of 241Am

A highly charged ion (HCI) has a large potential energy, which is equal to the binding energies of all the elec-trons removed to create the ion. When such a slow HCI approaches and then enters into a solid surface, an \abovethe surface" and a \below the surface" hollow atom will be formed, respectively, by capturing electrons from thesurface into its empty levels. Not only new aspects of atom physics has been introduced by hollow atoms, but alsoHCI applications in material science has promising prospects, such as surface analysis, the synthesis of materialswith new properties, and the formation of nanostructure that have been an active area of research in recent years[1??6].

According to the classical over-barrier model[1;2], as a slow highly charged Xeq+ ion approaches a critical distance R =p 2q from the surface with the work function W, it begins to resonantly capture conduction electr... 详细信息
