低能电子可以是非常活泼的，因为它们被许多分子有效地捕获，然后经历快速的单分子分解。这种过程的横截面可以非常大，比电离或激发横截面大几个数量级。1，2在过去的二三十年里，人们对气相分子的电子附着反应进行了一定程度的研究。另一方面，在团簇中进行类似的实验只是最近才进行的。这一贡献的重点是在弱约束货车范德华集团的反应引起的低能（0-10 eV）电子捕获。特别强调的问题将放在如何的基本数量的这些过程（即附着能量，带负电荷的化合物的演变，并最终形成的产品的能量分布）的行为从一个孤立的分子在单一的碰撞条件下的一个分子聚集。
Low-energy electrons can be very reactive in that they are effectively captured by many molecules which then undergo rapid unimolecular decompositions. The cross section for such processes can be very large, several orders of magnitude larger than ionization or excitation cross sections. 1, 2 Electron-attachment reactionsto molecules in the gas phasehave been studied to some extent within the last two or three decades. Analogous experiments in clusters, on the other hand, have only recently been performed. This contribution focuses on reactions in weakly bound van der Waals clusters induced by low-energy (0-10 eV) electron capture. Particular emphasis will be placed on the question how the basic quantities of such processes (ie attachment energy, evolution of the negatively charged compound, and energy distribution of the products ultimately formed) behave on pro-ceeding from an isolated molecule under single collision conditions to a molecular aggregate.
