论文摘要
在远程Rydberg电子状态中，RB $ _2 $的绝热势能曲线是使用Twiel-Electron \ textit {R} -matrix方法[M. Tarana，R.Xurík，物理。 Rev. a \ textbf {93}，012515（2016）]在35 a.U.和200 A.U.将结果与零距离模型进行比较，以找到范围内距离的区域，在该区域中，费米的伪能力方法提供了准确的能量。原子perturber的有限范围电位模型用于计算Rydberg电子的波函数，并确定了研究特定于研究的核对间距离范围的特征。
The adiabatic potential energy curves of Rb$_2$ in the long-range Rydberg electronic states are calculated using the two-electron \textit{R}-matrix method [M. Tarana, R. Čurík, Phys. Rev. A \textbf{93}, 012515 (2016)] for the intermediate internuclear separations between 35 a.u. and 200 a.u. The results are compared with the zero-range models to find a region of the internuclear distances where the Fermi's pseudopotential approach provides accurate energies. A finite-range potential model of the atomic perturber is used to calculate the wave functions of the Rydberg electron and their features specific for the studied range of internuclear distances are identified.
