摘要 斯德哥尔摩大学正在建造一种新型低温静电存储装置,该装置由两个具有公共直线部分的离子束存储环组成,用于研究带相反电荷的离子在低且明确的相对速度下的相互作用。在这里,我们考虑使用这种新工具来测量在星际离子化学中,特别是在宇宙前生命离子化学中重要的相互中和反应的横截面和速率系数的前景。
Abstract A novel cryogenic electrostatic storage device consisting of two ion-beam storage rings with a common straight section for studies of interactions between oppositely charged ions at low and well-defined relative velocities is under construction at Stockholm University. Here we consider the prospect of using this new tool to measure cross-sections and rate coefficients for mutual neutralization reactions of importance in interstellar ion chemistry in general and specifically in cosmic pre-biotic ion chemistry.
