Abstract :
Unexpected two-quantum resonances are observed in potassium vapor using two-dimensional Fourier-transform spectroscopy. These transitions are an unambiguous indication of many-body interactions, which arise from the long-range interatomic coupling that is responsible for resonance self-broadening.
