论文摘要
基于广义的局部框架变换，开发了一个高度激发的Rydberg分子的详细理论框架。我们的方法避免使用伪电势并产生人体框反应矩阵的分析表达式。后者用于获得分子势能曲线，但同样可以用于光解离，光电离或其他过程。为了说明治疗的可靠性和准确性，我们考虑了RB $^* - $ rb rydberg分子，并将我们的治疗与最新的替代方法进行比较。作为第二次应用，目前的形式主义用于重新分析SR $^* - $ SR分子的振动光谱，从而提供了对其性质的更多物理见解，并将结果与相应的测量结果进行了比较。
A detailed theoretical framework for highly excited Rydberg molecules is developed based on the generalized local frame transformation. Our approach avoids the use of pseudopotentials and yields analytical expressions for the body-frame reaction matrix. The latter is used to obtain the molecular potential energy curves, but equally it can be employed for photodissociation, photoionization, or other processes. To illustrate the reliability and accuracy of our treatment we consider the Rb$^*-$Rb Rydberg molecule and compare our treatment with state-of-the-art alternative approaches. As a second application, the present formalism is used to re-analyze the vibrational spectra of Sr$^*-$Sr molecules, providing additional physical insight into their properties and a comparison of our results with corresponding measurements.
