论文摘要
$^4 $ he $ _2^+$分子离子的旋转间隔在其$ x \^2σ_\ text {u}^+$地面电子状态下是通过包括非耐绝热，相对性和领先的量子 - 电动动力学的校正来计算的。对于振动基态的旋转激发序列和基本振动，观察到理论和实验的良好一致性。计算最低能量的旋转间隔为$ 70.937 \ 69（10）$ cm $^{ - 1} $与最近报告的实验值一致，$ 70.937 \ 589 \ 589（23）（60）（60）_ \ text {sys} $ cm $ cm $^{ - 1} $^{ - 1} $ [l。 Semeria，P。Jansen，G.-M。 Camenisch，F。Mellini，H。Schmutz和F.

The rovibrational intervals of the $^4$He$_2^+$ molecular ion in its $X\ ^2Σ_\text{u}^+$ ground electronic state are computed by including the non-adiabatic, relativistic, and leading-order quantum-electrodynamics corrections. Good agreement of theory and experiment is observed for the rotational excitation series of the vibrational ground state and the fundamental vibration. The lowest-energy rotational interval is computed to be $70.937\ 69(10)$ cm$^{-1}$ in agreement with the most recently reported experimental value, $70.937\ 589(23)(60)_\text{sys}$ cm$^{-1}$ [L. Semeria, P. Jansen, G.-M. Camenisch, F. Mellini, H. Schmutz, and F. Merkt, Phys. Rev. Lett. 124, 213001 (2020)].
