我们提出了一个完全精确的非相对论计算的能量和波函数的J = 1状态的HD+分子离子。获得的能量具有非常高的准确度（10 - 14 Au），对于大多数能级来说，比之前的计算提高了几个数量级。我们计算了J = 0态的静态极化率，与文献中的结果相一致，并提高了计算精度。我们还计算了J = 0态之间的双光子跃迁几率和光位移。最后，我们将我们的研究扩展到更高J态之间的跃迁，使用跃迁概率的近似表达式，并讨论了HD+中双光子光谱实验的可行性。
We present a fully exact non-relativistic calculation of the energies and wavefunctions of the J = 1 states of the HD+ molecular ion. The energies are obtained with a very high accuracy of 10−14 au, representing, for most levels, an improvement by several orders of magnitude over previous calculations. We compute the static polarizabilities of the J = 0 states, which are in agreement with the literature, with an improved accuracy, as well as the two-photon transition probabilities and light shifts between J = 0 states. Finally, we extend our study to transitions between higher J states, using an approximate expression of the transition probability, and discuss the feasibility of a two-photon spectroscopy experiment in HD+.
