Level structure of 164Dy from the (n, n′γ) reaction

Abstract

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 164Dy(n, n′γ). The scheme of levels and gamma transitions in 164Dy 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 n π = 02 + and 11 + rotational bands is found to be violated. The nature of the 2+ level at the energy of 1796.68 keV is discussed.
