论文摘要
我们考虑对与氢分子离子中的自旋轨道和自旋旋转张量相互作用相关的超细系数的更高校正校正。 $Mα^7 \ ln（α）$ - 订单辐射校正是在NRQED框架中得出的。我们介绍了完整的数值计算，包括$Mα^6 $ - 订单相对论校正，对于H $ _2^+$。相对于Breit-Pauli水平，理论不确定性降低到一个ppm的一个数量级以上。我们还将结果与可用的RF光谱数据进行了比较。
We consider higher-order corrections to hyperfine coefficients related to the spin-orbit and spin-spin tensor interactions in hydrogen molecular ions. The $mα^7 \ln(α)$-order radiative correction is derived in the NRQED framework. We present complete numerical calculations, including as well the $mα^6$-order relativistic correction, for the case of H$_2^+$. The theoretical uncertainty is reduced by more than one order of magnitude with respect to the Breit-Pauli level, down to a few ppm. We also compare our results with available rf spectroscopy data.
