Relativistic corrections of order α2 to the g factor of H2+ are calculated with a high accuracy of nine significant digits for a wide range of rovibrational states. The precision of previous calculations [R. A. Hegstrom, Phys. Rev. A 19, 17 (1979) is improved by about five orders of magnitude by performing nonadiabatic variational calculations and by including recoil corrections. These results allow for nondestructive identification of the internal state through the measurement of spin-flip transition frequencies, which is a crucial requirement for proposed spectroscopy experiments on H2+ and its antimatter counterpart H¯2 in Penning traps [E. G. Myers, Phys. Rev. A 98, 010101(R) (2018)]. Further, they pave the way towards precision calculations of the g factor through the calculation of higher-order QED corrections and hence to an alternative precision route to obtaining the proton-electron mass ratio.

顺序的相对论修正 α2G 的因素 H2+以九位有效数字的高精度计算,适用于广泛的振动状态。先前计算的精度 [R. A. Hegstrom,物理。Rev. A 19 , 17 (1979) 通过执行非绝热变分计算和包括反冲修正,改进了大约五个数量级。这些结果允许通过测量自旋翻转跃迁频率来无损识别内部状态,这是提出的光谱实验的关键要求H2+ 和它的反物质对应物 H¯2-在 Penning 陷阱 [E. G.迈尔斯,物理。修订版A 98,010101(R)(2018)]。此外,它们为精确计算G 通过计算高阶 QED 校正,从而获得获得质子 - 电子质量比的替代精度途径。
