Abstract: The possibility of existence of ultranarrow atomic and nuclear radiative lines in a "megaatom" of a Bose — Einstein condensate in a quantum trap is estimated. This phenomenon is caused by the elimination of the inhomogeneous broadening due to suppression of the random motion of atoms in the condensate resulting from the establishment of the higher-order quantum coherence in it.
