    "abstract": "The ac Stark effect was used to induce resonant energy transfer between\ntranslationally cold Rydberg atoms. The Rb Rydberg atoms were obtained by laser\nexcitation of cold atoms from a magneto-optical trap. Using two-photon\nmicrowave spectroscopy of the 49s_{1/2}-50s_{1/2} transition, the field\nstrength of a 28.5 GHz dressing field was calibrated. When this dressing field\nwas set at specific field strengths, the two-atom dipole-dipole process\n43d_{5/2} + 43d_{5/2} -\u003e 45p_{3/2} + 41f was dramatically enhanced, due to\ninduced degeneracy of the initial and final states. A series of observed\nresonant field strengths correspond to different magnetic sublevel\npossibilities for the initial and final states. These agree well with\ncalculated resonance fields based on a perturbative ac Stark shift formula.\nThis method for enhancing interactions is complementary to dc\nelectric-field-induced resonant energy transfer, but has more flexibility due\nto the possibility of varying the applied frequency.",
