Magnetically induced anions of rare gas clusters and polar molecules

在磁场存在的情况下，中性体系可以附着一个额外的电子，形成一个在无场空间中没有类似物的阴离子。到目前为止，这种磁感应阴离子已经被研究用于原子。该项目致力于对完全由外加磁场形成的复杂中性物种的阴离子进行理论研究。稀有气体原子团和极性分子将被讨论。我们预计，我们的研究将产生条件，在这种条件下，可以形成稳定的、具有显著结合能的阴离子，以满足现代实验室提供的磁场强度。将特别注意那些在无电场空间中没有稳定的阴离子对应物的物种的阴离子。这一结果有望对一般的阴离子实验具有直接的相关性，并刺激对外加磁场支持的阴离子状态的实验研究。这些结果在大气、等离子体和星际物理以及化学反应动力学中的具体应用是可以预见的。

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.
