研究了 (12)C(4+) 离子撞击对尿嘧啶分子以及纯尿嘧啶和纳米水合尿嘧啶簇的裂解。这项工作的重点是复杂系统的碎片行为和环境的影响。一方面，发现周围尿嘧啶或水分子形式的环境对碎片动力学具有显着影响，提供整体“保护”效果，而另一方面，我们观察到特定碎片通道的开放。特别是，我们报告了对一系列水合碎片的首次观察。这表明尿嘧啶和水分子之间存在强烈的相互作用，使水簇与观察到的分子碎片结合。
The fragmentation of uracil molecules and pure and nano-hydrated uracil clusters by (12)C(4+) ion impact is investigated. This work focuses on the fragmentation behavior of complex systems and the effect of the environment. On the one hand, it is found that the environment in the form of surrounding uracil or water molecules has a significant influence on the fragmentation dynamics, providing an overall 'protective' effect, while on the other hand we observe the opening of specific fragmentation channels. In particular, we report on the first observation of a series of hydrated fragments. This indicates a strong interaction between uracil and water molecules, holding the water clusters bound to the observed molecular fragments.
