Rubidium pure long-range ion-pair molecules

The Rb2 ion-pair satellite band located in the blue wing of the rubidium second resonance doublet line was observed in the absorption measurements of a dense rubidium vapor. The observed satellite band was identified as a long-range ion-pair state, by using the Rb2 longrange potential curves based on ab initio calculations. In order to perform the semiclassical spectral simulations of the observed satellite band, the relevant Rb2 long-range potential curves and corresponding molecular dipole oscillator strengths were calculated using the asymptotic method. The importance of the observed satellite band (long-range ion-pair state) is discussed in connection with the formation of Rb2 ultracold molecules.
