Theoretical studies are proposed of systems in which an electron sees simultaneously two forces of comparable strength. One study involves high doubly excited states in atoms, another the effect of a magnetic field on high singly ionized states. In these systems the combined potential is non-separable, and novel analytical techniques are required. Adiabatic and WKB methods will be used, also diagonalization within degenerate basis states and mapping to linear differential equations. Long sequences of doubly excited states out to very high excitation and near-zero-energy resonances in a magnetic field will be calculated.

理论研究提出的系统，其中一个 一个电子同时受到两种强度相当的力。 一项研究涉及原子的高双激发态，另一项研究涉及原子的高双激发态， 磁场对高单电离态的影响。 在这些系统中，组合势是不可分的， 需要新的分析技术。 绝热和WKB 方法将被使用，也对角化内退化 基态和映射到线性微分方程。 很长的双激发态序列 磁场中的激发和近零能量共振 将被计算。
