Non-Rotational States Of Dy-164

The level scheme of Dy-164 up to about 2.6 MeV energy is analyzed, using experimental data obtained in (n,gamma), (n,e(-)) and (n,ngammagamma) reaction measurements at the high-flux reactor ILL Grenoble, as well as the (n,n'gamma) reaction data, measured at the IRT reactor in Salaspils. The structure of low-lying levels of Dy-164 is interpreted in terms of two-quasiparticle states, interacting with collective excitations of axially-deformed core.
