摘要: 主要揭示了不同电离机制对高电荷态离子单电离和多重电离的贡献 ,包括直接电离 (一步过程 )、激发 自电离 (两步过程 )以及内壳Auger过程 ,研究了高电荷态镨离子的电子碰撞电离. Electron-impact ionization of ions is one of the most fundamental processes in every kind of plasma. Especially in high-temperature plasmas-whether in laboratory (nuclear fusion) or in astrophysics (atmosphere of stars)-atoms become ionized into multiply-charged ions by electron impact. The main purpose of our investigations is to unravel the contributions from different ionization mechanisms-like direct ionization (one-step process), excitation-autoionization (two-step process) and...
