标题： Bound states of negatively charged ions induced by a magnetic field

摘要： 我们分析了负离子的束缚态，这些束缚态被预测存在是由于磁场的存在，由Avron等人提出。 我们确认在无限重核近似下，这样的态的数量是无限的，并通过结合绝热和微扰理论的方法提供了对基本物理图景的见解。 我们还计算了相应的结合能，对于角动量为零和非零的态，这些结合能在定性上有所不同。 提出了包括质心效应情况的展望。 显示英文摘要

摘要： We analyse the bound states of negatively charged ions which were predicted to exist because of the presence of a magnetic field by Avron et al. We confirm that the number of such states is infinite in the approximation of an infinitely heavy nucleus and provide insight into the underlying physical picture by means of a combined adiabatic and perturbation theoretical approach. We also calculate the corresponding binding energies which are qualitatively different for the states with vanishing and non-vanishing angular momentum. An outlook on the case of including center of mass effects is presented.
