The fragmentation of neon dimer induced by low energy O⁶⁺ ions

We have investigated the fragmentation channels Ne⁺-Ne⁺ and Ne²⁺-Ne⁺ from Ne₂ dimer induced by O⁶⁺ ions at impact energy of 15 keV/u. The Ne⁺-Ne⁺ fragmentation channel mainly results from three pathways: the interatomic coulombic decay of Ne²⁺(2p⁴)-Ne initial state, the direct columbic explosion and the radiation charge transfer. Nevertheless, the fragmentation channel Ne²⁺-Ne⁺ is predominant by the direct coulombic explosion. (paper)
