Abstract

We present the study of the catalysis effect in the resonant energy transfer between ultracold 85Rb Rydberg atoms. We have investigated the energy transfer process of 34p + 34p → 34s + 35s, and observed Stark-tuned Forster resonances. When additional Rydberg atoms of 34d state are included in the interaction, an increase in the population of 34s states atoms is observed. Although the 34d state atoms do not directly participate in the resonant energy transfer that produces 34s state atoms, they add an additional interaction channel 34p + 34d 34d + 34 p that is resonant for all electric fields. We have also investigated the time dependence of the resonant interactions of 34p → + 34p → 34s + 35s, compared the experimental results with the numerical simulations of simple models, and found them to be in good agreement.
