In the presence of a magnetic field, a neutral system can attach an extra electron to form an anion which does not have an analogue in field-free space. By now, such magnetically induced anions have been studied for atoms. The proposed project is devoted to theoretical investigations of anions of complex neutral species formed exclusively due to the presence of an external magnetic field. Clusters of rare gas atoms and polar molecules will be addressed. We expect that our studies will yield conditions under which stable anions with significant binding energies can be formed for magnetic field strengths available at modern laboratories. Special attention will be paid to anions of those species which do not have stable anionic counterparts in field-free space. The results are expected to be of immediate relevance for experiments on anions in general, and to stimulate experimental search of the anionic states supported by external magnetic fields. Particular applications of the results are foreseeable in atmospheric, plasma and interstellar physics as well as in chemical reaction dynamics.

在磁场的存在下，中性系统可以附加一个额外的电子，形成一个在无场空间中没有类似物的阴离子。到目前为止，这种磁致负离子已经被研究为原子。拟议的项目致力于理论研究的复杂的中性物种形成的阴离子完全是由于外部磁场的存在。稀有气体原子和极性分子的集群将被解决。我们希望我们的研究将产生条件下，稳定的阴离子与显着的结合能可以形成磁场强度在现代实验室。特别注意的是那些在无场空间中没有稳定阴离子对应物的物种的阴离子。这些结果预计将直接相关的实验上的阴离子一般，并刺激实验搜索的阴离子状态支持的外部磁场。特别应用的结果是可以预见的大气，等离子体和星际物理以及化学反应动力学。
