摘要
在研究HD_2^+与固体膜的相互作用时,发现在HD_2^+穿过固体时产生了较强的尾流效应,并在确定HD_2^+的结构时,尾流效应起到了关键的作用.这一技术的使用,可以使得许多使用传统方法无法确定的分子离子结构寻求到一种方法和手段.本文就如何使用尾流效应来确定HD_2^+结构作一报道.这种方法的基本思想是,库仑爆炸能谱图谱相对于分子离子的核间距时非常敏感的.
In the study of wake effect resulting from the reaction of HD＋ with thin carbon foil, we find one striking use of wake effect is that it can be applied to determine the structure of micro-cluster ions which cannot be detected use normal Coulomb Explosion technique only. In this paper, we report this method of determining the triatomic molecular HD＋ by using the new theoretical model of wake effect for triatomic molecular we proposed. The basic idea of this method is that the pattern of the coulomb explosion spectrum is very sensitive to the nuclei separation of micro-cluster.
