Oscillating electric fields at 1.356 and 28.5 GHz were used to promote the resonant energy transfer process: $43d_{5/2}+43d_{5/2} \rightarrow 45p_{3/2}+41f$ between translationally cold $^$Rb Rydberg atoms. The ac Stark shifts due to these dressing field created degeneracies between the initial and final two-atom states of this process. The ac field strength was scanned to collected spectra which are analogous to dc electric-field-induced resonant energy transfer spectra. Different resonances were observed for different magnetic sublevels involved in the process. The exact choice of dressing frequency and structure of the spectra are more readily understandable for the lower frequency (1.356 GHz). |
