The population of sidebands in 160Dy has been observed following the 161Dy( 58Ni, 59Ni) 160Dy reaction. The intensity of discrete transitions in these bands, identified using particle-γ−γ coincidence measurements, was found to be weak compared to the ground-state band. A peak of width 500–600 keV at about 1 MeV, observed in the NaI spectra, is attributed to the decay of two- quasiparticle states to the ground-state band. A second peak at 400–500 keV is attributed to transitions between 2-quasiparticle states.
