Lithium in strong magnetic fields
摘要：
研究了锂原子在0 <= gamma <= 10的强磁场中的电子结构。我们的计算方法是一个完整的配置相互作用方法的基础上的一组各向异性高斯轨道，非线性优化每个场强。给出了基态和几个激发态的总能量和单电子电离能的精确结果，这些基态和激发态分别对应于每种对称性^20 ^+、^2（-1）^+、^4（-1）^+、^2（-2）^+、^4（-2）^+、$^4(-3)^{+}$。这些能量作为场强的函数的行为进行了讨论和分类。线性和圆偏振过渡的过渡波长。
英文摘要：
The electronic structure of the lithium atom in a strong magnetic field 0 <= gamma <= 10 is investigated. Our computational approach is a full configuration interaction method based on a set of anisotropic Gaussian orbitals that is nonlinearly optimized for each field strength. Accurate results for the total energies and one-electron ionization energies for the ground and several excited states for each of the symmetries ^20^+, ^2(-1)^+, ^4(-1)^+, ^4(-1)^-, ^2(-2)^+, ^4(-2)^+, $^4(-3)^{+}$ are presented. The behaviour of these energies as a function of the field strength is discussed and classified. Transition wave lengths for linear and circular polarized transitions are presented as well.
