氩二聚体binding energies的动量空间计算
Momentum space calculations of the binding energies of argon dimer
摘要：
通过求解动量空间中的齐次Lippmann-Schwinger积分方程，计算了氩二聚体的结合能。本文利用Patkowski { \it et al.}不仅证实了由其他小组预测的氩二聚体基态（即$j=0$）的八个氩二聚体振动能级，而且还提供了用于确定第九态结合能的非常精确的方法，其值是讨论的问题。我们的计算也被扩展到更高的旋转量子数$j$的状态，我们已经计算了所有174个束缚态的能量为两个潜在的模型。我们对氩二聚体基态振动能级的数值计算结果与其它理论计算和现有的实验数据符合得很好。
英文摘要：
The binding energies of argon dimer are calculated by solving the homogeneous Lippmann-Schwinger integral equation in momentum space. Our numerical analysis using two models of argon-argon interaction developed by Patkowski {\it et al.} confirms not only the eight argon dimer vibrational levels of the ground state of argon dimer (i.e. for $j=0$) predicted by other groups but also provides a very precise means for determining the binding energy of the ninth state which its value is a matter of discussion. Our calculations have been also extended to states with higher rotational quantum number $j$ and we have calculated the energy of all 174 bound states for both potential models. Our numerical results for vibrational levels of the ground state of argon dimer are in excellent agreement with other theoretical calculations and available experimental data.
