By employing a beam of reactor fast neutrons, gamma-ray spectra and angular distributions of gamma rays with respect to the neutron-beam axis were measured in the reaction {sup 164}Dy(n, n′γ). The scheme of levels and gamma transitions in {sup 164}Dy was composed on the basis of data published earlier and new levels, rotational bands, gamma transitions, and multipole-mixing parameters. It is concluded that the scheme of J = 0–4 levels is complete up to the excitation energy of 1.95 MeV. The commonly accepted rule in constructing K{sub n}{sup π} = 0{sub 2}{sup +} and 1{sub 1}{sup +} rotational bands is found to be violated. The nature of the 2{sup +} level at the energy of 1796.68 keV is discussed.
