We consider quantum electrodynamics (QED) corrections to the fine splitting E(2P_{3/2})-E(2P_{1/2}) in the Li atom. We derive complete formulas for the mα^{6} and mα^{7}lnα contributions and calculate them numerically using highly optimized, explicitly correlated basis functions. The obtained results are in agreement with the most recent measurement, helping to resolve discrepancies between former ones and lay the foundation for the investigation of QED effects in light, many-electron atoms.
我们考虑了锂原子精细分裂E(2P_{3/2}) - E(2P_{1/2})的量子电动力学（QED）修正。我们推导了mα^{6}和mα^{7}lnα贡献的完整公式，并使用高度优化的显式相关基函数进行了数值计算。所得结果与最新测量结果一致，有助于解决先前结果之间的差异，并为研究轻的多电子原子中的QED效应奠定基础。
