Popis:	We theoretically investigate the feasibility of using intensity distributions of light of a single laser beam diffracted by a circular aperture as optical dipole traps for cold neutral atoms. Localized and cylindrically symmetric traps on the central axis of the circular aperture exist for both blue- and red-detuned laser light. Experimental mapping of the spots of interest using ${\mathrm{CO}}_{2}$ laser light demonstrates the existence of these light distributions for laboratory conditions and their agreement with theoretical predictions.
