Ultralong Rydberg Cs$_2$ Molecules Investigated by Combined ab initio Calculations and Perturbation Theory

Vibrational properties of ultralong Rydberg Cs $_{2}$ molecules are investigated on corresponding potential curves obtained by perturbation theory. The Rydberg Cs $_{2}$ molecules are associated by a Rydberg Cs( $n S / n P$ ) atom $(n = 30 - 70)$ and a ground state Cs( $6 s$ ) atom. The starting point for the perturbation treatment of corresponding Rydberg molecular potential curves is to generate accurate atomic Rydberg states from realistic {\it ab initio} effective core potential. The calculated results have similar characteristics with available experimental and theoretical investigations on Rydberg Rb $_{2}$ molecules. And this is the first time that Rydberg molecules are studied at the {\it ab initio} level.
