利用１７０ＭｅＶ的Ｓ(９＋)与Ａｒ原子气体靶发生碰撞反应，采用高能离子引起的多重电离的飞行时间技术，测量了反冲离子相对产额，并与多体经典轨道蒙特卡罗理论的计算结果进行了对比分析，发现理论低估了较高电荷态反冲离子的产额。
The collision reaction of S (9+) with Ar atom at 170 MeV was carried out, and the relative yield of recoil ion was measured by the multi-ionization time-of-flight technique induced by high energy ion. The results were compared with the Monte Carlo theory of multi-body classical orbit A comparative analysis was carried out and found that the theory underestimated the yield of higher charge state recoil ions.
