The modifications of the angular spectrum of an intense Bessel beam caused by its self-action in nonlinear medium are revealed. The appearance of a central spot and outer ring in its angular spectrum was observed. Experimental results obtained for benzene are in good qualitative agreement with the theoretical predictions.
