Precision spectroscopy in few-body atomic systems, like hydrogen and helium, enables the testing of the quantum electrodynamics(QED) theory and determination of the fundamental physical constants, such as the Rydberg constant~\cite{2013H}, the proton charge radius~\cite{2009Biraben_HydrogenReview}, and the fine-structure constant~\cite{2010Pachucki,2017Zheng}. It also sets constraints on new...

As the simplest system, Li+ has significant application in verifying the quantum electrodynamics (QED) theory and determination of the fine-structure constant, because the spectrum of Li+ ion can be calculated accurately in theory. We constructed a low energy Li+ source by electron bombardment, and energy of the 7Li+ ions is 500 eV. The 1s2s 3S -1s2s 3P transitions of 7Li+ are investigated by...
