Experimental evidence for collision-induced superradiance.
An experiment performed on barium atoms has permitted us to observe an infrared emission whose spectral and temporal analysis has led us to identify it with collision-induced superradiance. Tentative theoretical interpretation is given in the dressed-atom formalism using the monochromatic approximation.
