用实验和理论方法研究了锂原子核激发态的激发和衰变。相关的远紫外光吸收光谱，这是观察到的部分解决的振动结构，解释的基础上的组态相互作用（CI）计算。此外，这些状态的自电离研究了喷射电子能谱和解释通过使用一个固定的玻恩-奥本海默模型。沿着与讨论的核心激发态的电子结构的相关电位曲线和1 s电离电位的理论测定。
The excitation and decay of core-excited molecular lithium has been investigated by experimental and theoretical methods. The associated far-UV photoabsorption spectrum, which was observed with partly resolved vibrational structure, was interpreted on the basis of configuration-interaction (CI) calculations. In addition, the autoionisation of these states was investigated by ejected-electron spectroscopy and explained through the use of a stationary Born-Oppenheimer model. A theoretical determination of the related potential curves and the 1s ionisation potential is presented along with a discussion of the electronic structure of the core-excited states.
