| 摘 要： | 采用飞行时间符合技术测得１．５—７．５ＭｅＶ非全裸碳离子轰击氦原子，引起氦原子双重电离与单重电离的相对截面比。对碰撞过程进行多体经典轨道蒙特卡罗模拟，得到相应的Ｏｌｓｏｎ—Ｓｃｈｌａｃｈｔｅｒ曲线，结合本实验结果，给出非全裸碳离子引起氦原子双重电离和单重电离的绝对截面，并进行了讨论。

| Abstract: | The ratios of the double to single ionization cross sections of helium impacted by partially stripped Cq ions (q=1,2,3,4)in energy range of 1. 5 - 7. 5 MeV were measured by using the time of flight procedure. The n-body classical trajectory Monte Carlo calculation was carried out to get the Olson-Schlachter scaling. The single and double ionization cross sections of helium were obtained by comparing the cross section ratios of the present work with the Olson-Schlachter scaling. |
