摘要
用飞行时间符合技术测量了１．５－７．５ＭｅＶ非全裸氟离子与氦原子碰撞引起的氦的双、单重电离相对截面比，对非全裸离子核外电子对碰撞过程的影响进行了讨论。对碰撞系统还进行了多体经典轨道蒙特－卡罗模拟，得到氦的双、单重电离绝对截面。
The double-to-single ionization ratios of He induced by partially striped F q+ (q=1,2,3,4) projectiles with energies ranging form 1.5-7.5 MeV were measured using TOF(time-of-flight) technique. the influence on the collision by electrons bound to the projectiles were discussed. The n-body classical trajectory Monto Carlo calculation was applied to the same collision system. The results of CTMC calculation were analyzed and discussed.
