170MeV硫离子入射引起的反冲氩离子产额

Abstract

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 yields of ionized argon atoms induced by 170MeV S~9+ ion impacts werestudied by using time-of-flight technique. The experimental yields of recoil Ar ionswere compared with the theoretical results of n-body classical trajectory MonteCarlo(nCTMC) method it was found that the nCTMC underestimated the yields ofhigher charge states of recoil ions.国家自然科学基金!19704012;;中国科学院“九五”基础研究重点资助!KJ952—S1—45
